    Are 170mm cranks (as opposed to 175mm) a bad idea for me?

    I can get a great deal on some Truvativ Holzfeller cranks for my XL Vp-Free but only in 170mm. I've only ridden 175mm on my trail bike and I'm 6'7'' tall. Would i really notice the difference? Will the 170mm be OK? Thoughts?

    6'7"??? I would think that you'd want something like a 180mm crank, not a 170mm crank. Check this out:

    or try this:

    Crank Length(mm) = 5.48 x Inseam(in)
