The derailleur clutch works opposite the suspension so it does contribute at least a small amount to inhibited suspension even if it’s not “pedal kick” per se. Hypothetically since ochain damps chain forces, it could also help your derailleur not whip around quite as far (ergo therefore etc your derailleur stores less energy), so there could be some overlap there

The Chances of Daprela ending up at pivot whilst Siegenthaler is still involved is 0 - not to go back to shite talking about rumours but she was maybe the strongest hater of daprela when all “that” info came out

One possible improvement to the article would be to add citations where you say stuff like “There has been a lot of research into crank length…” Another would be to then admit that these primary sources are mostly from cycling contexts other than mountain biking, and so generalizing from road to mtb requires caution. Another option is to avoid the issue by not doing pinkbike style pseudoscience that claims to explain everything in mtb in authoritative style. Exploring questions well is worth way more than giving chatgpt answers with an equation copied out of your old physics textbook.

You have to define "harder" to answer that question properly. If your talking about power, then the answer is no - if you spin the shorter crank faster, you make the same power (power = force x velocity). You don't actually consume more watts with a shorter crank, so in that sense you're not more tired at the top of the climb. IF you run out of gears, then yes, it will be more difficult to turn the crank over in really steep sections. On more mellow, steady climbs, I actually found it was less "hard" to get to the...

I don't know where you get the idea that NA is more technologically advanced than China. At least on the electric car front, China's putting out better products than the US or Germany from what I've read.

Ideally you’d get data on a slow chunky section, a fast chattery section, and a fast chattery section where you slam on the brakes for ~2 seconds. People tend to disregard high speed sections because they assume the hub will never engage, but that stop being true as soon as your wheel stops spinning freely.

My hunch is the same. Usually when people ride their bike chainless they report that they could go up in damping/spring rate. I’m thinking get data from normal control runs, and data from chainless runs, and those should be your upper and lower limits for suspension performance. I’d expect to find that the better the pedal kick solution, the closer...

Hey Charlie, it just occurred to me that in practice, pedal kick does not actually manifest as pedal kick. It manifests as encumbered suspension. If you want to see the on trail effects of different pedal kick solutions, you should get some data acquisition for your rear suspension and ride a very repeatable section of trail. You’d be able to...

Could you do an accelerometer on an ochain? Knowing the mass and radius of the chainring, you’d be able to calculate the peak force being applied from the chain with the peak acceleration of the chainring. You’d be able to convert that to force at the feet with crank length too.

I feel that heavy braking is the largest contributor/least discussed for pedal kick. The situation where you might be locking up the rear brake but still using a good amount of travel is the exact situation where you’d really want your suspension performing at its best
