Kit includes caliper, sprocket/rotor, hardware and weld-on frame tab. Calipers are supplied with a bushing making them suitable for ¾”, 1” or 25mm axle applications. All our sprocket/rotors are supplied with a standard 1.98” center hole. Some wheels have a larger indexing lip on the hub, but there is no ‘standard’ size. We will bore the sprocket/rotor center hole to your requested size for an additional $50. We can bore the center hole as large as 2.5”.

Although designed for use on rigid and Softail applications, we also use Sprocket Brakes successfully with traditional swing-arms on bikes such as Dynas. If you are considering this, then the following information may help. Dimension from outer face of sprocket to outer face of caliper is 1.2”. Caliper measures 2.9” across at it’s widest point, 3.6” at it’s longest point, and is 2.55” from front to back. We are frequently asked whether oil from the chain causes a problem. Firstly, with modern ‘O’-ring chains you cannot lube the joints as they are sealed. You need simply to keep the side-plates clean. Fly-off from the chain is in an outward direction, so contamination only occurs during lubing, if you do lube your chain. If it does, wipe it off. Finally, if some oil makes it onto the braking surface it burns off immediately. In reality, therefore, the contamination issue does not cause a problem. We use RK heavy duty ‘X’ring chains on our bikes; great looks, low maintenance.

Our Sprocket Brake Kit uses readily available brake pads and seals.
