Has anyone experimented with different crank arm lengths?
170 mm seems to be the standard... So for comparison now I've switched to the shortest ones I had, the 152mm (6") crank that came on my Kent magnesium folder. As you'd expect, not much leverage; but great for spinning! I may actually stick with this one....
Hello Rudi.
Mike Burrows, a UK bicycle designer who at one period worked for Giant, has. He has an article in this quarter's edition of "Cycle", the UK journal from the CTC organisation about crank lengths & he quite likes shorter ones like you've tried. I'm still looking for some to try on our bikes.
