Hey! What is the biggest differences in crank size from 170mm, 175mm and 180mm? I am lookign into buyign a new one and was wondering what the pros and cons are of the different sizes? I have been out of the sport for over 2 years now with work and college no time to ride but I'm gettign back into things again. Thanks for any advice!

It depends on how tall your leg is. You measure from the inside of your crotch to the floor.
If its 21" its 144mm crank length
22" is 150mm crank length
23" is 155mm crank length
24" is 160mm crank length
25" is 162mm crank length
26" is 166mm crank length
27" is 171mm crank length
28" is 175mm crank length
29" is 177mm crank length
30" is 180mm crank length
31" is 182mm crank length
32" is 185mm crank length
34" is 190mm crank length
