MRP SXg Chain Device Mountain Bike Chain Guide with Skid Plate

The MRP SXg Chain Device represents a significant advancement in chain guide technology, engineered to deliver exceptional chain retention and protection without compromising on weight or efficiency. Designed for riders who demand reliability and precision, the SXg excels across diverse mountain biking disciplines, from aggressive short-travel trail riding to the challenging terrains of Rampage courses. Its innovative design ensures stable chain retention and robust chainring defence, making it an essential component for any serious mountain biker.

Incorporating advanced Whippersnapper technology, the SXg eliminates moving parts in the lower guide, thereby reducing friction and enhancing drivetrain efficiency. The upper guide is constructed from full-size, co-moulded nylon HD, which provides superior durability while minimising noise and wear. Available with either aluminium or carbon backplates, this chain device offers options that balance cost with stiffness and strength. The integrated SX skid plate further protects the chainring from impacts with rocks and trail obstacles, ensuring long-lasting drivetrain integrity. For installation and maintenance, the SXg requires only a single 4mm HEX wrench, simplifying adjustments and upkeep. Compatible with a broad range of chainring sizes and chainlines—including Boost 148—the SXg fits seamlessly on most modern mountain bikes.
