DMR DMR Speed Guide

The Speed Guide is a classic piece of DMR design…simple, dependable, reliable and race proven. The Speed Guide combines the functions of the Chain Cage and Chain Reactor into one robust and easy to set up chain device. The sealed bearing PU pulley and adjustable lower arm keep your chain in close contact with the chainring and the Stainless Steel cage keeps things under control at the top. Available in BMX BB size too.
