I've got the R451, but the front one is on it's way out. The cable clamp bit will move 3-4mm before braking begins. Seems as though I may of damaged the cable clamping bit tightening it. Less than impressed, but braking has been good with them. Barely been used though!
Looking for alternatives, the Tektro R539 came up. But are they better or worse than those Shimano R451?
I'd buy the R650, but I want black ones and they don't make them.
Theres also the TRP RG957, but they are up to 3x the price of the others! Bit much.
