    Is a 180mm crank acceptable in place of a 165mm?

    I am trying to decide if I should bid on a 3 piece crank set on Ebay. I verified the length of the 1 piece crank on my Trek is 165mm, so I am looking at another 6/10". Would this be acceptable on the Dyno Glide project?

    Fixed or SS? As a general rule you usually stay shorter w/ fixed, longer w/ SS. Also depends on your leg length.

    i'd imagine 180 will feel quite a bit longer and different than the 165s, if that's what you're used to and what fits you.

    NO! Don't buy it. Those cranks are waaaaay too long for you. Only Jan Ullrich runs 180s.

    Check out http://www.peterwhitecycles.com/fitting.htm for a good place to start. If you already had it laying around, I'd say go for it. Since you're purchasing one, at least look for some 170s.

    My guess is that with your height, 180 is too long.

    Inseam is around 30", thanks for the link I'll take a look.

    I did not measure my Fisher Aquila but will do that tonight, if feels OK but I'm am more concerned about pedal slap on the Dyno Glide.

    if you're going for torque, and it's not a fixed gear bike, 175-180mm is just about right for a 30" inseam for certain types of riding. if you're looking at bmx cranks, which i suspect you are if they're 180mm, it might be hard to find an economical set of 170mm. you could find a set of 175mm much easier.

    That's awesome. I doubt it's really doing them any good. Biomechanics being what they are and all...
