Another thing to look at is crank length.

You might choose from:
155mm
160mm
165mm
170mm
172.5mm
175mm
177.5mm
180mm



The most common sizes today are from 170mm to 175mm. But, there are a few outliers. It will depend a bit on your height, leg length, personal preference, etc.

In that case, when consider pedal to ground, or toe overlap, you don't divide by two. So, a 170mm crankset will be 5mm higher off the ground than a 175mm crankset.

Although, one frequently raises the seat for shorter cranks, and lowers the seat for longer cranks (based on the lowest position of the crank arms).
