DA 7700 brakes don't open enough to let a 25mm tyre out!

aha! That makes more sense than a whole new caliper model number just for a different locknut! Yes, I think you can even see that the pinch bolt assy might swing further on the photos of the back of the calipers. I guess BR-R450 mayn't open wide enough to let a 32mm tyre out when it is mounted on a narrow rim...?

cheers

R451 calipers will not allow a 32mm tyre through it with the QR open, we've had to let the tyre down significantly to do so.
