The problem is that I can't adjust the pads close enough in to need a QR with my 25mm tires. The brake levers mean that if I did the slightest touch would activate the brake. Thus the caliper is at it most open position already. This means that the QR has no real function. Still I can't complain. The Dual pivots work a million times better than the single pivots even with mismatched levers. I really LOATH the feel of those cheap crappy single pivot POS's - especially with the brakes levers they came with. Adjusting the pads to within mm of the tire didn't even make a difference in their worthlessness. Give me V brakes or Discs any day of the week.
