NOTE, I have 40lbs of brake pads for most popular brakesets. I have tested them all, oem as well factory pads. I specialize in balancing brakes front to rear for the best performance suited to the riders needs. If you dont see it here, ASK!
I have various brake pads, many of them for Code and Guide brakes. Original Sram Sintered, Galfer PRO and E-bike, MTX ceramic Red and Gold, Jagwire Pro Extreme, and others. The best price is when you buy 4 sets, $10-$20ea. Individual sets are $15 to $25.
I am a brakes system tester, with a 30lb box of brake pads for all brakes. Message for a recommendation.
