To clarify I've bought a Quarq Riken R GXP crank, with a view that I'll get SRAM GXP pressfit bearings to fit into the Canyon Aeroad.
I also want to swap these cranks on to my winter bike as well.
I've asked Canyon to clarify and their response wasn't worthy of a repeat....but here's info they sent:
BOTTOM BRACKET BEARINGS
All frames (except Aeroad CF): BSA/BSC 1.370x24T, (right cup left hand threading!)
Aeroad CF: Pressfit BB 91 with 86.5 mm
Common cartridge bearings can be mounted directly into the bottom bracket shell of all models with high- grade grease. Observe the torque specifications of the bottom bracket manufacturer.
