Ultegra Triple Crank Info Needed???

[speedemon]

I started the process of ordering my new bike. The bike is a 53CM frame, but the crank they said I need is a 175mm crank arm which they're out of. How important or difference is the 175mm oppose to the 172.5mm crank arm? Can someone give me some detail info on this.


Thanks

If the frame you're ordering is a 53cm traditional style (not compact), you should probably be riding 172.5's anyway. How tall are you, or if you know, what's your actual inseam? Not the size pants you wear, but from the floor to your crotch.
