Chain guides are one of those things that are easily forgotten until something goes really wrong. With the T.M. Designworks Factory Edition 2 Rear Chain Guide you’ll get a guide that outlasts the competition and protects your mounting brackets at the same time. With a body design that is stronger than even solid-bodied guides, the Factory Edition 2 is arranged so dirt and debris fall out of the guide and away from your chain to keep wear low. The rub block is made from T.M. Designwork’s "Zero Chain Drag" plastic that has super-slow wear and promotes consistent chain tension. It’s also replaceable if you somehow manage to wear it out. Pick up T.T. Designworks’ Factory Edition 2 Rear Chain Guide when you want a buttery smooth chain guide trusted by pros and amateurs alike.
