If I remember correctly Avid found that if they punched the enter holes out they nearly always squealed under braking, so they just stopped stamping it out. Great bit of engineering.
That’s correct. It was only for that year’s rotors, and only really a problem with the 203mm (and to a lesser extent 185mm) rotor. They’ve gone back to a stamped-out design this year.
I have one on the front end of my bike and initially thought it was a manufacturing fault, but confirmed it with Transition (who also weren’t very happy with the design). The thing weighs a bloody ton, but has worked well so I’ve stuck with it.
Edit: and the bike looks great, by the way. Striking without being flash. Very nice.
