Product info
The Speedco M2 Disc Brake Mounting Kits are CNC machined out of 6061 aluminum. Each kit includes one disc brake mount, three axle blocks, and two chain-tension screws/nuts. These mounts are compatible with a size 120mm disc rotor, and will not work with a 140mm disc rotor. For optimal braking performance, we always recommend a Shimano XT/XTR hydraulic braking system. There are three kits available which are 10mm, 15mm and 20mm. Please select carefully based on your rear hub's axle configuration.
