Finally a mechanical disc brake for mountain bikes and fat bikes that offers superior performance and is a snap to set up. The Spyke is a dual sided mechanical caliper where both pads actuate providing even and precise clamping force. This results in even pad wear and easy pad adjustment with the addition of a barrel adjuster. No longer is adjusting the whole caliper necessary as the pads wear. All of this in a 169g (per caliper) package that works with all linear pull levers. Caliper and mounting bolts included only.
