Chung | It's been studied quite a bit but usually from the perspective of muscle shortening speed so searching for "crank length" won't always find the right studies. But perhaps this little empirical experiment is closer to what you had in mind: bikeblather.blogspot.fr/2014/07/… | |
| Jul 2, 2014 at 5:51 | comment | added | Móż | @R.Chung I didn't realise it's been studied so much, I couldn't find anything when I looked (and I've looked before, too). That's also one possible explanation for the lack of clear results/summaries. | |

Chung | The Martin et al. study looked only at max power but the results have been the same for submaximal power: over a wide range of crank lengths, submaximal power does not appear to be affected. That means you can choose crank length on other criteria, including personal preference, clearance or cornering issues, fitting or range of motion issues, or even because a crank is on sale, without worrying that it will decrease sustainable power. It also means that changing crank length won't increase sustainable power. Which is to say, it's been studied a lot. | |

| Jul 2, 2014 at 1:27 | comment | added | Móż | @mattnz I suspect I am in the same position, but power meters are still too expensive and I don't have a consistent enough regular ride to even estimate. I really should have a go at this next time I've got access. I wonder if I can make TriSled sponsor some research. | |
| Jul 2, 2014 at 0:37 | comment | added | mattnz | I found on 145's I could maintain higher cadence and speed (therefore poweroutput) for longer and have since gone down to 165 on my bike (MTB), I am 1.75cm / 65kg. My personal feeling is crank length is understudied and '1 size fits all' suits the manufacturers ad shops best, so "the rule about crank lengths is no one talks about crank lengths". | |
