Hi, I just bought two 160mm £8 each shimano RT61 rotors (http://www.chainreactioncycles.com/M...px?ModelID=815) to replace my tektros (£13 each) (http://www.chainreactioncycles.com/M...?ModelID=34829) that got bent in the car. I kept bending them with a crescent wrench, but somehow they kept returning to their warped state. Anyway, I just got the new shimanos, bolted them on, went to dial in the pads and about 40% of the front and 30% of the rear rotors are slightly bent. Any reason why, or am I just being fussy? I like sharp brakes, and when I run the pads close enough to the rotor to get the desired stopping power the above (rough) %s are rubbing. If it helps, I'm using tektro aquila and avid bb7 mech calipers. Thanks.
