Side note: Rumors were that the big LA had 20min+ values above 7.5, which is pure alien. The 5min test is hell, because one stresses _all_ energy systems in the human body to their maximum effort. So you ride in pain after something like 30 secs till the finish, which feels eternal.
The 20min test is more easy compared to that, as it is very close to your general endurance. Thus, a top rider these days would rip his legs & mind out, when climbing besides the former LA.
- wiredfool 10y agoWell, my 5 minute number is how long it takes me to climb a steepish local hill, when I'm doing a few reps. So it's imprecise, and there's like one significant figure. 250-300 watts is my guess. And half as fast as cat3? Yeah, I could see that. My point still is, it's possible to calculate the upper limit on losses from wheel flex under power load, and I'd assert that they are small enough to not matter. And what's more, the effect of torsional spring type flex goes down (at a constant power output) as speed goes up.
