Go to part for my E bike.
I have a fast 1500W Ebike. I use the BB7 brakes with SRAM metallic pads. They're quiet, last 5x as long, and require 5x less adjustment. I also use Shimano RT86 ICE Tech rotors. If you have a fast or heavy Ebike these are great too. On the BB7 you will have to trim the tab on the inner pad to use.. It's worth spending some time getting good cables and housings set up with no extra play. Once set up all adjustment is done at the caliper. I've been running these brakes for 20 years. They simply don't quit. With the right pads and rotors these are stillhigh performance brakes
