  1. Renault confirmed a software fault on Vettel's car caused the ICE to ERS to malfunction. This resulted in a drive-ability issue on the car. When he put his foot down he was never sure if he was getting full power only a part thereof. They will require most of the evening to correct the problem. For an understanding of how these complicated systems are working in 2014 I cut and paste from Formula1.com Long-time fans of Formula One racing will be familiar with the concept of a Kinetic Energy Recovery System (KERS), technology that was introduced to the sport in 2009 and was a mainstay from 2011. KERS worked by harnessing waste energy created under braking and transforming it into electrical energy, providing an additional 60kW (approximately 80bhp) of power for up to 6.67 seconds per lap. The Energy Recovery Systems (ERS) which form an integral part of an F1 car’s power unit from 2014 take the concept of KERS to another level, combining twice the power with a performance effect around ten times greater. ERS comprise two energy recovery systems (Motor Generator Unit - Kinetic [MGU-K] and Motor Generator Unit - Heat [MGU-H]), plus an Energy Store (ES) and control electronics. The motor generator units convert mechanical and heat energy to electrical energy and vice versa. MGU-K works like an uprated version of KERS, converting kinetic energy generated under braking into electricity (rather than it escaping as heat). It also acts as a motor under acceleration, returning up to 120kW (approximately 160bhp) power to the drivetrain from the Energy Store. MGU-H is an energy recovery system connected to the turbocharger of the engine and converts heat energy from exhaust gases into electrical energy. The energy can then be used to power the MGU-K (and thus the drivetrain) or be retained in the ES for subsequent use. Unlike the MGU-K which is limited to recovering 2MJ of energy per lap, the MGU-H is unlimited. MGU-H also controls the speed of the turbo, speeding it up (to prevent turbo lag) or slowing it down in place of a more traditional wastegate. A maximum of 4MJ per lap can be returned to the MGU-K and from there to the drivetrain - that’s ten times more than with 2013’s KERS. That means drivers should have an additional 160bhp or so for approximately 33 seconds per lap.
  2. Both of these that I have started and completed I ran tubeless tyres and Time ATAC or Shimano XTR pedals. All those components have proved bullet proof
  3. Whatever works for you on a one is what you should use on the other. An Engines power and torque profile is generally unchanged irrespective of the chassis its fitted to.
  4. maybe try using one before spreading drivel. I used a Thudbuster for 5 years and never hurt my knees. because of it. You are not bouncing around as you seem to suggest. Like I said, stop talking ***
  5. still no answer to a civilised question so I guess antagonism is the way forward.
  6. Cycling and aggression are becoming synonymous..
  7. Just because the Pro's don't use them doesn't make it loess of a good idea. Inexperienced riders are more likley to fall and crash and generally have not learnt how to fall properly. Watch guys like Minaar, Hannah, Smith et al, and see hwo they tuck and roll when they fall. its the same with professional rugby players, most don't wear helmets or face guards but many do. Does the few that make it ok for experienced kids at high school to not wear them. You're right it is your choice but that does not make the word "need" inappropriate
  8. Cane Creek's Thudbuster as pictured has been around since the late 90's. I have one from 2001. They are a very good product but have not been popular since dual suspension bikes started getting to reasonable weights. The Thudbuster can be set up so that there is almost no movement while pedalling but that takes time and skill. I would recommend the Thudbuster if you have a HT and don't have the cash for a dualie. There's a lot less to go wrong with a Thudbuster but they are pretty heavy but certainly lighter than other suspension seat posts
  9. How old is your lightie? Going cheapest may not be in the interests of hs safety. MX helmets are too heavy for a childs neck. You will need a LEAT Brace as well.
  10. Rock Shox Solo Air and Dual Air are proven designs that work. Fox is always tinkering and leaving the end user to be the guinea pig. Sure they keep changing the names of the same tech but fact is the stuff just works
  11. With the size of the groups there is no shortage of people with delusions of Voightism that the average speed never really drops till the groups reach Chappies. By then the Voightists have fallen away leaving those with fresh legs to cover the two climbs at higher than normal pace.
  12. Lets approach this a different way. What would like the club to say in addition to what they have stated wrt: Condemning the vicious act suspending the members involved Handing those names over to WPCA and PPA plus Cycletour trust Co-operating fully with the investigation. The club has appointed an attorney to look after its interests and protect its dvelopment riders That attorney is not representing the implicated riders. The implicated riders have to sort out their own legal counsil
  13. not stoking a fire. Its a simple question.
  14. what needs to be said in addition to what has already been said?
  15. they did indeed wear other outfits
  16. then please write up a ride report that explains how your tactics works out for you include pitchas
  17. you need to chose your finger respectfully...
  18. I tend to find that a technique of looking ahead, seeing the moving obstruction (Also known as a jogger) coming my way, plan my next move by looking over my shoulder, sticking my finger out to show oncoming traffic that I am moving right and then do as I promised. and the jogger and I pass each other with mutual admiration and a smile while the motorist to whom I indicated my intent has not had a hissy fit...
  19. I swear I know that bike but they were quite popular. A old cycling pal had one just like it and I've not seen him for a couple of years. He works for IBM. I'll direct this thread to him and enquire. Looking at his time for the ride it could very well be his bike

    Argus 2014

    Most of the accidents I saw were due to: 1) MTB's hoggin the middle of the road and faster groups splitting to go around them. Someone always had to hit the brakes due to not seeing the slow moving brick on the MTB 2) stoopppid ijuts weaving between riders at 60km/hr from Smits to Scarborough. Eventually the inevitable happened
  21. yes there will be Spec 650B bikes in 2015
  22. LOL seems everyone is so damn uptight they forgot it was wooden spoon Friday.......eish
  23. The DA promised to improve Cape Town when the ANC faltered and failed to deliver. I can't believe that 20 years after democracy we still have 80's style thugs dressed as cops in Cape Town. That right there in that video is the type of thing the DA promised to fix. Doesn't seem that any party is capable of fixing this country
  24. we "guffawed" loudly afterward about the amount of airtime this incident is getting. Can't wait for Shaps article in RIDE
