My current setup is Deore hydros (either 515 or 525) with 8" Hope Gothic rotors. I'm having issues with modulation, alignment, and the 8" rotors are just overkill for what I ride (I'm 160 lbs).
I'm planning to change these out to BB7s (160 mm rotors) with Avid SD 7 levers.
I was told that mech discs are lighter. How much of a weight savings should I expect, just a couple ounces, or substantially more?
