Crank Questions

[tlaing1]

So I have to buy a new crank for my bike, and I was at Bikeworldusa's site and I have no idea what the sizes are. Is it arm length or is it the width of the crank holder?

My first build is going to have paint this weekend and maybe riding next week...... pics to follow.

it sounds like you are going with 3 peice cranks so we need to know what you are putting it into first. a pic would help
