One of my bikes has a Rohloff and 165 cranks. The other has XX1 and 145 cranks. I hate double chainwheels.
There is a company called Bikesmith to which you send your cranks and they send them back truncated. This is for those sick pervs who insist on double chainwheels. If you only want a single you can get a BMX crankset like the Sinz of Sharky. I have Redline.
