PowerTorque is like GXP but without the redeeming self extracting bolt for the splined crank. It's cheap and nasty. UltraTorque has an expensive but brilliant Hirth joint in the middle of the axle. It's the kind of joint you find in jet engines, and it's invention was a work of genius, but the cost of making it is too high to be competitive in the OEM market for bikes below ~£2k
