The good: Beautiful looking brakes with that nice, modern looking cable adjuster. Quick Release works great. Even the new fangled quick release's quick release works great. Easy to adjust and install. Works great. Lots of clearance above and around tires(see below). Comes with brake bolts and Recessed Allen nut. Comes with dollup of blue Loctiteish stuff on bolts. The Plenty: Just FYI in interested and wondering about this: Plenty (and I mean plenty) of clearance for 40mm Hetre and P45 Longboard fender under 52 Bleriot fork crown.
Just enough (but enough, which is all you need) for 44-584 Marathon and P45 Longboard under a 52 Sam Hillborne fork crown.
Only con, which really doesn't matter is: Stock black pads are not so good in the rain. Be sure to start slowing down early for stop signs and stop lights when in rainy conditions. Consider getting some salmon all weather pads. Keep the stock black pads as back up.
