Before I go down the route of floating rotors for the new bike, is this a common problem?
When I was on my hols earlier this year, I was pulled on the brakes and, to my delight, the braking surface thingy on my Hope rear floating rotor came away from the floating spider doodah and ended up as a mangled mess in my rear spokes. Only my incredible skillz prevented my certain death.
The lesson here, my friends, is check your rotors for wear more often than once every 5,000 km.
