I currently have promax mechanical discs and they are driving me nuts. I have been searching ebay for a better brake setup but only the caliper. I found a front avid mechanical caliper but i'm not sure if it will fit my rotor. I imagine they wouldnt be too diffrent and should fit. The rotor isn't oversized i'm not sure what size they are though. I don't want to shell out a mess of cash for a new set of discs because i plan on getting a KHS Witch DR or Banshee Chaperall.
I found a set of tektro calipers that are said to fit 160mm rotors. I would much rather buy due to the low price and the fact its a unused set.
Is 160 the "standard" size?
