The STS was developed to provide high strength impact capability for street and trail riders who frequently and intentionally smash into immovable objects. With its 36T capacity, the STS has become the favorite of aggressive riders everywhere.

Lightweight, durable aluminum back plate with upper guide and lower roller to keep chain on in extreme terrain

Designed specifically for 4-cross and dual slalom. The G45 is designed for riders that need a durable, reliable chainguide in a simple, lightweight package that is compatible with virtually any bike.

Designed to add an element of adjustability and compatibility, the System 2 uses a stationary, open inner ring to allow use of large chainrings on bikes that have a chainstay in the standard position, without having to install a longer bottom bracket.

This is the chain guide that started it all. Designed primarily for frames with elevated chainstays

The G2 showcases MRP’s patented integrated guard that allows the design to be super lightweight, without sacrificing chain retention, rigidity or protection of the chain and chain ring. The integrated guard fully protects the chain and also the rear pulley wheel.
