  1. Good morning Hubbers, Anyone know who will service Powertap products in Gauteng? I believe SRAM bought the name, and Bicycle Power has disowned the brand.
  2. Afternoon Hubbers! To those who own or have owned a Powertap wheelset, specifically the G3 ANT+ model, how does one do a software update? I have downloaded, just for the sake of the update, Poweragent. Then I remove the G3 cap from my rear wheel, which has a mini-USB port. I don't know what kind of cable to use to connect to my PC? I used several cellphone charger cables but the computer does not recognise it. Thanks!!
  3. SRAM plans to incorporate the PowerTap power meter products into the market leading Quarq product portfolio, including DZero power meters, ShockWiz suspension tuning assistants, and TyreWiz tire pressure sensors. “Way back in 2006 when I started Quarq, PowerTap was the dominant power meter solution. The accuracy and durability of PowerTap hubs were the standard of power meter performance and set a high bar for us to meet,” says Quarq founder Jim Meyer. “It’s very exciting to now bring PowerTap products into the SRAM/Quarq product family. The future product opportunities are enormous.” “We are proud of our accomplishments in the power meter sector,” Saris President and COO, Jeff Frehner, said. “We took a product category exclusively available to pros and made it accessible to all athletes looking to reach their highest potential. Today marks the start of a new generation of Saris. While PowerTap is leaving the Saris portfolio, we are excited to grow our product offerings across current and future categories.” PowerTap sales, support and service will continue without interruption during the transition. Saris will continue to sell and support the PowerTap product line from Madison, WI for a number of weeks during the transition period. After the transition period, SRAM will assume all sales and support of PowerTap from Spearfish, SD, home of the Quarq power meter team. Cape Cycle Systems can not make comment on the future of this acquisition in terms of sales and service until they are informed by SRAM – for now it is business as usual.

  4. I am looking for a local bike shop that is able to change the battery of a Powertap G3 power meter hub with the proper hub cap wrench in and around Cape Town please?
  5. The P1 measures cadence through a digital encoder, as there isn't an accelerometer. As with all PowerTap power meters, accuracy is claim to be +/- 1.5 percent. Communication with other devices is either through Bluetooth Smart (aka 4.0) or ANT+. The pedals are fully plug-and-play with the AAA batteries giving a claimed battery life of 60 hours. The right pedal is a "slave" pedal that passes it's data to the left pedal to transmit to the head unit. Each pedal has a LED indicator that will flash green once woken and connected or red in various patterns if there is a problem. When battery life reaches 20%, the P1 sends a low battery flag to your head unit, this warning should help prevent complete loss of battery. If the right pedal battery dies, the left pedal will double its output to create a power reading. If the left battery dies, there will be no power reading. Each pedal houses eight strain gauges in the steel axle, spinning on two needle bearings and one case bearing. According to PowerTap, the bearings should be good for many thousands of miles, but you can’t service them yourself. Serviceability is limited to external wear items like the claw, spring, pedal plate and battery cover o-ring. All other internal wear components must be serviced by PowerTap.In addition to the strain gauges built into each pedal there is a "Multipole Ring" sensor with 20 magnets positioned around each pedal spindle. This measures the application of force throughout the entire stroke and identifies dead spots and pedal-stroke inefficiencies. To date, PowerTap is yet to find a way to display this data, but they are working on it and it's certainly exciting to know the tech exists and comes already build in. A green LED indicates that the pedals are on and connected. It turns red when there are complications.

With Bluetooth, the Joule GPS+ can do a wireless upload to PowerTap's mobile app, which in turn can be linked to auto-upload to popular training sites like Strava and TrainingPeaks. With about 80 hours of internal memory your rides and info will remain safe until you next make it to your computer to transfer the data. The PowerTap Joule GPS cycling computer allows you to upload routes and receive turn-by-turn directions while riding your bike. To do so, create the route using any popular map creation software or website, export the route in .GPX or .TCX file type, and upload to the Joule GPS using PowerAgent.The Joule GPS+ was a joy to use. Simple to set up and understand, taking no time away from riding your bike. Pairing devices was quick and painless and once a connection was established it was rock-solid for the duration of my training. I didn't use the turn-by-turn navigation often, but when I did it was accurate and can be a bonus to riders training a specific route or when out exploring on your bicycle. The screen and the data views are highly configurable. In direct sunlight it does suffer a bit, but not to the extent where you can't see the display. It's route logging is accurate and the GPS signal is solid once acquired. VAM - How quickly the rider is climbing a hill. The rate of ascent in meters/hour. This feature is most effectively used in interval mode. Start an interval at the bottom of a large climb. Stop the interval at the top. See how quickly you're gaining elevation. Normalized Power (NP) - An estimate of the power the rider could have maintained for the same physiological "cost" if the output power was constant. IF - Comparison (ratio) of a ride's normalized power to the rider's threshold value. TSS - Training stress score: an estimation of a ride's total difficultly based on glycogen burned.

Recommended Retail Price: R1,495.00 I found the PowerCal a bit gimmicky. I think it will offer a rider a step into power training without the relatively high cost of a power meter pedal, hub or chaining, but for the serious athlete it is not accurate enough. By their own admission PowerTap say that the PowerCal is not as accurate as a power meter and is not intended to replace one. They say that research has shown varying degrees of accuracy based on individuals and types of riding. Fitting the P1 to a bike The pedals are calibrated at PowerTap’s US manufacturing facility and installation is the same as fitting regular pedals using a 8mm Allen key - no need for special tools. If you would like to use a torque wrench, make use of your crank's torque guide. The P1 pedals automatically detect the installation angle, accurate to within 0.5 degrees, and they also learn the crank arm length after a few revolutions using the built-in gyro. The pedal knows its position in the stroke, as the gyro gives a precise north/south tracking. PowerTap recommends that you manually zero the pedals before each ride.Release tension can be set using a 2.5mm hex wrench to adjust between a range of 6 – 20 Nm. The P1 pedal's stack height is 14mm, which is about 3-5mm greater than some other popular pedal systems on the market, so remember to account for this with your saddle height when moving to the P1. Elliptical or oval rings are supported with the P1. The P1 takes 40 individual angular velocity measurements and subsequently 40 power measurements per pedal stroke. Any acceleration/deceleration within a pedal stroke would be measured. Compare this to some other systems that assume constant angular velocity, which typically reports higher power when using non-round rings. On the Road Out on the road, the pedals work very well and in general use there is nothing that will give away the fact that they are not ordinary pedals. Clipping in and out is positive and, depending on the cleats you opt for, there is a good amount of float. PowerTap has ensured the pedals can stand up to plenty of abuse by testing them to extremes - from underwater to high weight loads, and they are confident the pedals can cope with whatever the most demanding cyclist can throw their way. To increase longevity, the metal plate on top of the pedal is replaceable. Once you have the Joule's screen set up to display the fields you would like to view, all you have to do is get going. The Joule GPS+ will start recording your ride as soon as it picks up that you're moving and, as explained above, the P1's will pick up crank arm length and exactly where it is in the stroke thanks to it's host of build-in sensors.Live left / right analysis while riding is great feature over and above pure power figures and that alone gave me enough to work on during the review period. It was especially interesting to see that one leg drops a greater percentage of power when the fatigue sets in. This information will not only help cyclists improve general strength and endurance, but help athletes recover from injuries and ensure that they do not put unnecessary strain on their legs or knees while recovering. Ground clearance is a non-issue to me and should be for most, if not all, riders and so to is the increase in weight (keeping in mind what you gain out of it). I have read comments about their ground clearance, but can't remember ever seeing any road bike rider scraping his pedals going around a corner. If you are that one in a million for whom it may be an issue, chances are that you will end up scraping the side of the pedal before the bottom. Verdict During my time using the pedals I have found them to be very accurate and consistent. There were no signs of spikes or false data on any of my rides, even though I used them in varying temperatures, on the road and on an indoor trainer. The pedals and accessories as tested are well made and the perceived quality is high, leaving me with the impression that it will last for many a season of riding and training.Having access to cadence, power, heart rate and left / right power data while training opens up a plethora of training options. You can now monitor strength training, efforts during high intensity interval training, look after yourself during recovery rides and work on not only increasing base fitness, but ultimate strength and peak performance too. All of this in an easy to use and set up pair of pedals and cycling computer. Left to right: Shimano PD-R540, PowerTap P1, and Look Keo 2 Max.

As with other offerings, Look Keo cleats can be used, but they ship with with proprietary 6 degree float PowerTap cleats and hardware. They also offer a 0 degree float cleat option as an extra accessory. Click here to view the article
  7. The combination of cold winter mornings and live coverage of the Tour de France makes training indoors the go-to for many cyclists and triathletes alike. Not only can you leave the thermals and toe caps off, but your indoor session can be just as effective (in certain cases, more effective), than training outdoors. There are a huge variety of training apps and aids out on the market, all designed to make your training easier, keep you entertained and make you want to train indoors. Although we are spoilt for choice with all the aids out on the marketing, let’s face it; training indoors isn’t nearly as exciting as getting out there. We know all the tricks in the book; from racing other cyclists online right through to watching the Tour in hope that it will inspire you to push through the next interval set. Although indoor training is mentally tough, there is one key factor that can change it for you. Music. The beat that drives your legs forward, the lyrics that transport you from the confines of four walls, the emotions that come from a few minutes of beautiful noise. Listening to music while you’re training can help your fatigue, boost your mood and helps you feel less pain. Choosing the right type of music for your training is what stands between you and the finish line. We want to know what your top three songs are for training indoors! Every week for the course of three weeks, we will award a pair of CycleOps socks to the best liked song list. At the end of the three weeks, we will award a CycleOps Winter Training Package to the overall top liked list. Turn up the music, close your eyes and let the beat take over. Submissions should be made in the following format, Artist, Song and Album (if known). The winner for each week will be announced every Monday (10th, 17th & 24th July 2017) with the grand price being announced on Tuesday the 25th July 2017
  8. Hi Guys Need some input on my indoor trainer set up. Being eyeing all the activity on Zwift activities etc and would like to enhance my current training experience if possible.. I currently have a Tacx Flow trainer which has served me well for a good few years now. It's paired with a Powertap so I am able to perform structured work outs with ease - via my Garmin. I generally just use the resistance settings of the trainer and my gearing to get into the required power zone. Is it at all possible to get a zwift / trainer road set up? I have being toying with the idea of getting a smart trainer but obviously feel that it might be overkill considering I already have the power meter? What would my options be? A cheaper smart trainer perhaps?
  9. PowerTap P1S The P1S represents a more affordable way to get the industry leading accuracy and reliability that has become synonymous with PowerTap. The P1S features a gauged left pedal and non-gauged right and like other unilateral power meters doubles the value of the single side to get total power. “While not as good as their bi-lateral brother, the P1, it is a great option to enjoy the simplicity and versatility that P1 users have grown to love,” said PowerTap product manager Justin Henkel. “And if down the road a cyclist decides they want bi-lateral measurement, the P1S will be upgradeable to dual-side measurement. There is no better way to introduce someone to power.” Retail price for the P1S is $699 USD (local ZAR still TBC) and will be available in late 2016. For up-to-date information on when the P1S will be available near you, please contact your local dealer or country’s PowerTap distributor. Advanced Pedal Metrics in PowerTap iOS Mobile App With dual-sided measurement, comes a host of new data. PowerTap’s new Advanced Pedal Metrics hands over the key to Pandora’s Box to unlock an entire world of pedal insights. Cyclists with a set of P1 pedals can measure parts of their pedal stroke that have never been measured before. Constructed to emphasize how one pedals a bike, Advanced Pedal Metrics shines a spotlight on biomechanics as it relates to how a cyclist moves their bike cranks and propel themselves down the road. In addition to gaining pedaling efficiency users will also get instant feedback on how position or equipment changes may affect how they pedal their bicycle. Pedaling insights will be shown in a force vector display, a heat map and polar plot. The Advanced Pedal Metrics are part of the new PowerTap Mobile iOS app, now sporting a completely new user interface. The newly redesigned PowerTap Mobile App also features a multitude of new visuals and functions aimed at helping cyclists get the data where they want it. PowerTap Mobile is a free application that can be downloaded to iOS devices from the Apple AppStore.
  10. For the last 17 years PowerTap has been creating the best power meters to give cyclists the edge that they’ve been yearning for. Last year PowerTap shook up the power meter market with the introduction of the P1 pedal power meter, the most advanced power meter ever developed. Today the Wisconsin-based cycling power meter manufacturer introduced two new products into their portfolio of pedal-based power meters. The first addition is a new power meter named the P1S, a single -sided version of the world-renowned P1 pedal-based power meter. The second is the much anticipated Advanced Pedal Metrics for P1 pedal users, available exclusively via the PowerTap iOS Mobile App. Click here to view the article
  11. If you’re anything like me indoor training can be a bit of a chore, but often the sensible option to supplement training through winter. Even with a decent trainer and the distraction of TVs or iPads, I quickly get bored and uncomfortable. Enter the CycleOps PowerSync and their Virtual Training software. Click here to view the article
  12. The CycleOps PowerSync is an electronically controlled resistance trainer. It’s able to simulate changes in gradient, yep, it can ‘make’ hills. And is programmable to create workouts or just increase / decrease resistance at the touch of a button or the tap of a screen. The PowerSync incorporates a power meter accurate to +-5% using the same technology found in the famed PowerTap variety. Coupled with the CycleOps Virtual Training (CVT) software your virtual cycling world expands. CVT allows you to choose from a multitude of interval, profile (hill) and heart rate based workouts, participate in realtime (or delayed) online races and go “out” on virtual video-based rides. Given my predisposition to avoiding indoor training I was keen to put these new tools to the test. Initial ImpressionsThe CycleOps PowerSync is a sturdy looking unit. Although I was testing on a very smooth surface, it has eccentric levelling feet which allow it to be stable on uneven surfaces. The mounting and operation is much the same as other trainers I’ve encountered. The bike is fixed to the trainer via the rear axle using a specially shaped steel quick release skewer. Adjustments can be made to suit the specific rear axle width The solid bolt-action fixing lever secures the bike in place The good news for mountain bikers is that there is a thru-axle adapter available, however it only supports 120, 130, and 135mm axle spacing and unfortunately no 29" wheels. For that you’d need to look at it’s bigger brother, the PowerBeam Pro, although you'd still be limited to a maximum axle width of 135mm. I tested the PowerSync with a standard 700c road bike and a 26" mountain bike (with a semi-slick tire). Both were easy to mount and had ample space on the rolling surface. The roller should fit tyres up to 2.25" depending on the profile and tread, although I'd opt for a smooth tire on the back from a noise reduction perspective. Models: ANT+ vs. BluetoothOur test unit is the ANT+ version and arrived with an ANT+ iPad dongle. This you’d have to purchase separately if the device you’ll be connecting to doesn’t natively support ANT+. There is also a Bluetooth model available, which although you would have an easier time connecting to, wouldn’t be as widely compatible with the majority of current sensors which are ANT+ based. Accessory: Climbing Riser BlockAmong the various accessories available from CycleOps is a Climbing Riser Block which our unit arrived with. This provides both stability and 3-levels of incline with the option to stack multiple blocks for greater inclines. Mounting a bike Mounting your bike on the PowerSync is pretty straightforward. You’ll first need to swop out your snazzy proprietary skewers or thru-axles for the relevant trainer compatible version. In the box you’ll find a standard quick release skewer included, but the thru-axle adapter would need to be purchased separately. The roller contact surface is smooth and visibly wider than most trainers I’ve used. It’ll comfortably support a wide mountain bike tyre, although for any bike a smooth, trainer specific tyre is recommended. With the bike mounted and power connected we’re just about ready to go. On the bikeGetting on the bike I first noticed the sturdiness of the setup. Although in part this was thanks to the climbing block, even without this accessory the PowerSync felt impressively stable thanks to it’s wide stance. The climbing block added noticeable stability upfront, to the point that I was more than comfortable to get out of the saddle and put a far more pressure on the bars than I'd dare to before. When the wheels start turning you’ll notice a blue led below the roller which lets you know you’re powered up and ready to connect to the app or another device. CycleOps Virtual Training Installing and setting up the CycleOps Virtual Training app was quite simple and intuitive. The app is available for IOS, Android and PC. For testing we used the IOS version on an iPad with the ANT+ iPad dongle. Although the app is a free download there is a $6 monthly subscription fee to maintain full access to all features, but you can start off with a free trial. Once you’ve registered with CVT and entered your profile details you’re good to go. You can then choose from various options for your indoor workout: Free Ride As the name implies in this mode you can decide how you want to ride. You get to adjust your target resistance as you’d like to either structure your own ad-lib workout or just ride. Profile Training If you’re keen to test your legs on a specific routes or just get some simulated hill training this mode will let you follow a real-world route virtually. The app adjusts the resistance automatically to simulate the ups and downs of the actual route. When I first jumped on the PowerSync I was sceptical about how this would feel. I chose my route, the Col d’Izoard, pressed go and hit the Pyrenees. This route is one of many that includes a video feed. When the video mode is enabled a video of the actual route will play based on your speed. You can either stream the video if you have a decently fast connection or download it beforehand. Sure enough as the road kicked up the going got tough. There is a slight delay between the on screen gradient change and what you feel as the resistance gets applied progressively. I was impressed by the difference. The uphills really do make you work and quickly had me searching for more gears as if on a real-world climb. Virtual Partner If you want a bit of company or some added incentive you can enable Virtual Partner. This feature allows you to select a previous ride from other users and compare your efforts. I did a ride around Gordon's Bay with Dipslick using a ride he'd recorded in 2014. You’re also able to quickly create your own routes based on your own GPS files, however this must either be done via the Virtual Training website or the Desktop version of the software. You can also create your own video routes via the desktop, but this is a little more complex. Workouts Power based training is said to be the most efficient and effective and the CycleOps PowerSync makes this easy for you. The Virtual Trainer allows you to select from various existing workouts or create your own. Each workout is based on a specific metric, either: Power, Power / Weight, % FTP or Gradient %. While you could do the same with a standard indoor trainer and power meter, the visual representation of the workout and on-screen cues thanks to the app take a lot of the thought out of it, allowing you to just ride. For anyone serious about their training or just wanting to make the most out of typically limited training time this is a most valuable feature. You can choose from various pre-existing workouts from other users The onscreen graphs and cues make interval training "easy". Or you can quickly craft your own workouts. Online Race Real time online races are one of the cool-factor features of the PowerSync and CVT app. Perhaps it’s a bit of nostalgia back to my misspent youth playing multiplayer computer games, but for me this is a great way to not only make indoor training more interesting, but create added incentive and commitment. Much like entering a real-world race it becomes all the more difficult to back out once you’ve put your name down. The races take place in real time on a predetermined course and use the data from your trainer to pit you against the other participants. You can compete with real people on the same course, at the same time from anywhere in the world. A group of Hubbers have been avidly running weekly races for some time now. FTP Test Thanks to the PowerSync’s built in power meter you're also able to perform a Functional Threshold Power (FTP) test. This test will allow you to establish your capability and then tailor your workouts based on the results. It also lets you benchmark performances and track progress. Be warned though - an FTP test is not for the faint hearted! The on-screen display mid-test Results from my somewhat feeble first attempt. Without the app: Connecting to a head unitIf you just want to ride or forgot to charge your iPad you can also simply connect to a compatible head unit. Most power meter compatible units will allow you to read power-data from the PowerSync, but wouldn’t allow you to set resistance as you could from the app. For this you’d need the PowerTap Joule GPS head unit which can control resistance. My Garmin Edge 510 had no issues connecting to the PowerSync and pulling in the available of power specific data. ConclusionThe CycleOps PowerSync indoor trainer is certainly not an entry-level trainer nor does it come with an entry-level price tag. Thanks to the workout tools and virtual riding / racing capabilities the CycleOps Virtual Trainer app makes riding indoors a pleasure, until the road kicks up that is. If you’re wanting to be a little more focussed and efficient with power-based training or you’re simply looking to spice up your indoor riding it might be worth stretching the budget for. The CycleOps PowerSync is available from Bicycle Power Trading either via their dealers in your area or direct on their website.

  13. So, I've recently treated myself to a pair of PowerTap P1 pedals. I've trained with them both on the road and on my IDT. I love the data and the real time feedback. I've suffered through a 20 minute FTP test and have that score. No problem here. On Sunday, I'm riding the R4V race. It will be my first with the power meter. What advice do the gurus on Bike Hub have for me in terms of using my new kit in the race.
  14. So, in a story that doesn't bear repeating (because it makes me feel really stupid), I damaged one of my 6 month-old Powertap P1 pedals. I took it to Dave @ Bicycle Power (the local agents) in Rivonia and explained that I was entirely to blame and could the pedal be fixed? They don't have a facility to do that kind of repair locally, so the pedals would need to be sent to the States. Dave proceeded to lend me a pair of demo pedal so I was not left with my power meters. He sent them to America where the one pedal was replaced in its entirety and the other was fully serviced. The pedals were returned with a brand new pair of free cleats (value R 350) The entire process took about 4 weeks, but I was not inconvenienced at all, as I was riding with their demo pedals. I got my repaired and updated pedals back today and the entire process cost just R 500.00. We spend lots of time deciding which products to buy for all our cycling exploits. We sometimes forget that service is as important a requirement as any other. When I am next in the market for an indoor trainer or power meter, there is only one place I will go to make my purchase - Bicycle Power. Thanks, Dave. Your service is exceptional.
  15. PowerTap PowerTap P1 Pedals Offering a unique solution compared to other power pedals on the market, the P1 pedals by PowerTap are self-contained units, having all the electronics and the battery, one AAA per side, contained in the 196g pedal. As with other offerings, Look Keo cleats are used . Communication with other devices is either through Bluetooth Smart (aka 4.0) and ANT+ and the pedals are fully plug-and-play. It automatically detects the install angle, accurate to within 0.5 degrees, and it also learns the crank arm length after a few revolutions using the built-in gyro.
