Current Projects chat and miscellany

Glad we got that sorted. You're both wrong.

If gain ratio is held constant, crank length is irrelevant over a wide range. It's irrelevant to acceleration rate, and irrelevant to constant speed.

The problem I have with this statement is that various people have done supposedly scientific tests and come to a different conclusion to this.

They may well be wrong, but you're not providing any evidence to back up your assertions. I don't expect you to do your own tests, although I'm sure they would be interesting, but you could at least provide some basis for your assertions. Otherwise it's just someone on the internet telling people they're wrong, which I tend to be wary of.

However, you have convinced me it's not worth worrying about too much and I will just go for 170mm for the new road bike and save fifty quid, I'm quite happy with that outcome so thank you for that...
