My 2011 Pinarello, rim brakes and all. Still does its job for me as a 62-year-old recreational cyclist. I cannot justify buying a new bike, but I have to admit, there's some gorgeous new bikes out there!

I do not know whether you came right, but I saw this advert you may be interested in. GoPro Hero 7 battery | Lights & Batteries | Bike Hub

Look at the last post in this thread:

It seems that the GoPro Hero 7 batteries will work on the GoPro Hero 8, but with a bit of caveats. Will the Hero 7 batteries work in the Hero 8 and/or Max?

I actually have no idea, there's no specs on Cycle Lab's website for this Marvel HRM. I also cannot find any website for the Marvel branded products. It seems Marvel is a CWC and Cycle Lab specific brand. On the Marvel's packaging it only indicates 1000 battery hours, ANT+ and Bluetooth and IP67 protection, which is similar to the Magene's specs

When I saw this post, linking to the one on sale at Cycle Lab, I decided to get it so that I have a spare available for whenever a replacement is needed. I had some soon to expire vouchers, I therefore paid only R488 with delivery included. It was delivered by Aramex couriers to my home in less than 24 hours after placing the order. When I opened up the Marvel branded box, it actually was a Magene H0003 model HRM that was inside. Picked up within a second by my Garmin Edge 130 Plus, and compared the readings with my Garmin HRM that I am currently using. Over a 5-minute period of wearing both, the readings were the same. Removed the battery and put everything back in its packaging and stored with my cycling goodies for when a need for it to be utilised comes.

What about getting it 3-D printed? https://www.thingiverse.com/thing:6250163

If I am not mistaken this can be configured using the Garmin Varia app. Garmin Varia™ App | Radar alerts

What's the diameter of the magnet? I have about 30 neodymium magnets in my drawer, 9mmX2mm. I am in Sasolburg. I used one of them on my Garmin GSC10 speed and cadence sensor but moved on to one without the need for a magnet.

I am a VERY average rider. On a good day I keep up with the cycling club's Saturday morning group ride on the shorter 68km ride at an average speed of 28-29km/h. Cycling solo to Parys and back to Sasolburg on a Sunday morning usually can be done in just under 3 hours, but depending on the always present headwind on the way back. I also am not a Group A or B bunch candidate, I am not even a Group AA or BB candidate😁. This year I am in group DD, departing at 07:33. But I am not fazed about that starting time and group, I am a recreational, almost 62 year old cyclist that just want to try and keep fit and doing my 18th "947" ride this year. Thanks for your guidance, I will have a good look at it but will probably not do any big changes with the RideJoburg world cycling championships in less than two weeks.

What alternatives would you recommend? I have always just used Energade because it's always readily available, but I am open to suggestions.

Very informative reads I stumbled upon. What & When to Drink to Ride Longer Exactly What to Eat and Drink After a Ride

I think you're right about that. Perhaps one banana probably isn't enough for a 3 hour, 85km bike ride. I admit I do tend to not eat enough when out cycling.

Yesterday I had a true taste of the effect that heat, and wind has on cycling. I could not join our regular club ride on Saturday morning and went out on my own on Sunday morning. I did check the weather prediction for the day, which did indicate high temperatures and 25-30km/h winds, so I decided to go out early and by about 05:15 I was out on the road. I went out on a route I have done many, many times, cycling from Sasolburg to Parys and back, a round trip of just over 80km. The first warning sign was when I saw my cycling computer showing a temperature of 28 degrees even before I got to Parys, and constantly battling the wind, which came from the side. Arriving at Parys, I stopped and i ate a banana and had some Energade. Whist cycling from Sasolburg I regularly had a sip of my water bottel which had an electrolytes tablet dissolved in it. Before venturing back I thought about topping up my liquids at the shopping center's toilets, but thought I had a enough to get back home. That bad decision was a big mistake. About 13 km from home, I depleted all of the fluids I had. And my cycling computer indicated a temperature of 34°C. Plus I had the side-wind that did not help me at all. At about 5km from home my mouth and throat were totally parched. When I got back into Sasolburg I stopped at the Shell garage, filled my 750ml bottle and completely drained it within a few seconds. I refilled it, and then took on the last 3km back to home. Arriving back home, I had a glass of water with an electrolyte tablet dissolved in it, and also a big glass of ice-cold water to rehydrate. I was totally out of energy when I got back home. This morning my upper leg muscles are a bit stiff from yesterday's battle against the wind and enduring the heat. One thing's for sure, I will never ever attempt to cycle back to Sasolburg from Parys without first refilling my water bottles! My almost 62 year old body didn't take too kind to the abuse I subject it to yesterday...🫤

Road bike, 10 Speed Ultegra 6700 (I think🤔). Front big chainring. No idea how many KMs, but was replaced May this year after being used since I got the bike in February 2011. Probably >40 000km. Front small chainring, not yet been replaced. The cassette was replaced 4 times in the ±13.5 years I have had my road bike. Each time an original Shimano cassette, but not always Ultegra. Currently Ultegra 11 - 28 cassette The chain was replaced about the same interval as the cassette. Since day one of owning my road bike, I have only used the Liqui-Moly dry chain lube, but recently switched over the Squirt chain lube. We'll see how that goes.
