Hmmm. Been watching a dvd from 2007 about setting your bike up. According to the presenter's calulations, I should be riding on 180mm cranks. Shocked

I use 170mm cranks and my absolute inside leg is 845mm. Now, while I have often debated with Matt Wyles whether or not I should be using 172.5mm cranks, 180mm is the biggest length I know of and way wide of the mark!

I'm going to research this subject a bit more and will keep this forum posted. Remember: Just coz you bought a bike with 175mm or whatever length cranks doesn't mean they are right for you! Suspect

You are Big Mig. 180mm cranks with a 60 tooth outer ring, I can see you now, Martin the grinder.

What is your fixation with Miguel, Mr Beck? I could have sworn all his best rides were with a certain European gruppo...

Anyway, I've found better formula for crank length:

(Absolute inside leg in cm x 1.25) + 65 = Ideal crank length in mm.

Round up if you if you are a heavy rider, round down if you are a light one. Very Happy

I do sound a bit fixated with Indurain, don't I. It stops here and now. You've worked out a formula for crank length? Don't bring that up as a conversational gambit on your next date with one of your ladies will you.

is that in high heels or trainers? alien

according to the calcs I should have 165 cranks - that would be on all four bikes!...........and at my level would it make a difference?....methinks not. Thats not taking into account most pairs of legs are of differing lengths etc. etc. Depth of different shoe soles...the list goes on.

More important to get on yer bike.....and ride! alien
