    will this allow to go from 170mm to 180mm rotors ?
    JAV on Oct 17, 2016
    BEST ANSWER: I'm not sure.  I was going from 160mm to 180mm rotors and these worked perfectly.  I think it also depends on the year the original brakes were made.  My bike was a 2014 bike.
    This says it doesn't come with bolts and I can't find the appropriate ones on the site (or at all). Any hints?
    dpwrussell on Dec 17, 2016
    BEST ANSWER: Hey Douglas,
    I've linked to a few options that should work for you. These bolts are all standardized so brand doesn't really matter. What does matter is that you use M6 bolts (6mm diameter x 1mm threading) in whatever length you need for your frame and caliper. Generally that will be around 12mm for most frames/calipers.
