    Smaller riders, what crank length?

    Building a bike for my 5' tall wife. Have any of you smaller riders ever tried cranks shorter than 170mm?

    I noticed Gary Fisher specs their 13" women specific bikes with 170s, but I wonder if something shorter might be better for someone who is flat out 5 foot?

    I know the crank length has a lot to do with wether you like to spin out or mash, but is one possibly more comfortable?

    I'm 5'5"... I run 170mm cranks on my BMX bike and it is better to run a slightly shorter crank on a MTB.


    I hate trying to spin my 175mm Truvativ Blaze Cranks.


    I paid for a $710 bike and got Truvativ "comfort" cranks. I am gonna slap someone at Specialized...


    Shorter the better... it will be harder to start spinning because of less leverage but she will be able to spin standing up if the need arises and she will feel less choppy.


    Cheers,
    Zach

    So, how short should we dare go? I have seen some of the older (seperate bb) XT cranks out there in 160, 165, and 167.5.

    Hmm... what kind of riding?

    If it were me? 165's.... so I would say that for her too. I don't wanna act like a know-it-all.. at 13 years old, but I DO know my fair share of these things.

    I use 165 cranks - I'm a tad shorter than your wife (4'10") -- my inseam is 26.75" and I really like them. I'm using xtr on my current bike - but on my old bike i had xt.

    i'm 5'2" and use 165 cranks on my geared bike, and 170s on my SS. it means i hit my pedals all the time when i switch to the SS from the geared bike. for spinning (geared), the 165s are perfect for me. I think they would suite your wife fine too.

    5'1", 31" inseam and i run 170s on all my bikes including my single speed.

    i wouldn't recommend shorter cranks unless your wife is really, really short (and despite what some may think 5'0" is not really really short! ). i have a friend who is 4'10" and i think she may run 165s, but all the other smaller women i know run 170s.

    It's sounds like 170 will be good. That is cool because 170s are pretty easy to come by. Not so mush for the 165s and shorter.
