I want to get more intentional about my fitness and measuring my performance and whatnot. As such, I'm in the market for fitness tracking technology for the first time.

However, I'm very much a Free Software / self-hosted sort of person, and I'm very un-thrilled about how proprietary all this stuff seems. It looks like the sensors themselves are kind of standardized ("ant+", whatever that is), and some of the data formats can be imported and exported, but the bike computers themselves and the companion apps and the online services appear to be trying to become walled gardens.

Short of building a bike computer from components myself, what hardware and software should I be looking into?

Edit: my most immediate concern is figuring out what bike computer to get, to be able to log data from the ANT+ speed, cadence, and heart rate sensors I've already bought (along with a GPS track). I'm considering anything from a Wahoo ELEMNT Bolt V3 ($300), to an off-brand(?) one like a Magene C506 ($100) or iGPSSport BSC100S ($38), to using my smartphone with an ANT+ dongle and the "A Training Tracker" app (Github, Play Store).

Good day!

I'd be interested in buying earphones that can block wind while in a call and bicycling.
For Android, and preferably under 60 euros.

Any ideas?

A good turnout for critical mass today

Youtuber "Brad is Brad" creates a custom controller for Subnautica using an exercise bike and an Arduino so that he has to pedal the bike in order to swim in the game.

An exploration of the unusual phenomenon of bike seat sniffing, its psychological implications, and the XJD brand's role in cycling culture.

This is an annual cross-state ride called RAGBRAI. It's been going for 52 years now. Riders typically use support teams, but I ride self-supported from the center of the state, ride half the route, and ride home. More photos:

Transportation officials have removed a growing list of safety materials that mention bike lanes from federal websites. Safety advocates warn that's undermining proven measures for reducing crashes.

The agency said Rapp and a fellow bicyclist were riding on a local road when Medina passed them in his car, stopped, and drove his vehicle in reverse. Medina then hit Rapp, and she was pronounced dead after emergency responders brought her to a hospital.

any cycling deaths a tragedy, seems this was intentional though ? what a cnut :(

20 miles like it's nothing

This is the best bike I've ever owned.

edit: after doing some renewed research, it might be a Mario Confente frame. I guess he partnered with major brands and produced limited edition models. If that is the case, it was a partnership with Bianchi and Campagnolo

Today while patching a leak, I noticed my tube is for 25-32 tyres, and my tyre is a 35. Is that really an issue? I wasn't aware of my mismatch, and I have driven quite a lot on these wheels with no noticeable problems. Now i'm just wondering if I should keep using this tube (it has two patches now).

Edit: also, the reason I was patching it because it lost maybe half of the air in ~48 hours, so not a massive hole but still a hole. I suspect it was from a piece of glass, which I thought i saw on my tyre but now seems to have come out (I had to get to work so I had no time to patch it immediately when i noticed the leak, it kept air in well enough for my commute).

I just measured my chain stretch for the first time and it exceeded my tools max measurement. So I bought a new SRAM PC830 chain and upon opening the box, discovered the sticky nature of factory grease. Which would be catastrophic for my dusty desert commute! So obviously, that has to come off. I consulted the web and found a brilliant website with charts for various chain lubes. https://zerofrictioncycling.com.au/

I ended up following KMC's advice and cleaning the grease off with a light oil (WD-40 was handy). Then a wet lube (I forget the brand; whatever my LBS stocks).

Frannie is a 2019 Salsa Vaya.

Steel frame with a Shimano 105 drivetrain. We roll tubeless. She typically hauls between 20 and 40 pounds of gear depending on the season. I used to ride carbon, but once I hit my 40s every ride started to hurt a little more, so I moved to steel. Unloaded, the frame weighs about 19 lbs, but it handles smooth as silk.

I would spend 8 hours a day on this thing if I didn't have a job.
