Powertap disc hub means I'm limited to a 160mm rotor. I've been looking to change to Shimano brakes for ages but the Maguras still work so I'm loathe to upgrade. Well, they did work, now they're not so good :)
How does the hub limit the rotor size?
They're special 8-bolt rotors to clear the Powertap electronics.
Proprietary interface, rotors only produced in 160mm.
edit - fat man beat me
