MRP G5 SL Mega Chainguide ISCG-05, 36-40t

When we're charging full-throttle down black diamond tech lines or launching into steep chutes, we count on the MRP G5 SL Mega Chainguide to keep our drivetrain protected and dialed. As the fifth generation of one of the most decorated chainguides in downhill history, the G5 SL Mega brings race-proven reliability to any aggressive setup. Built with a stiff alloy backplate and a fiber-reinforced bashguard, this guide absorbs serious abuse while maintaining chain security via a full upper guide and a lower pulley system. The pulley keeps chain tension steady through rough terrain, and the HD2 upper guide is co-molded to dampen noise. With support for 36-40T chainrings and a clean ISCG-05 mount, this guide is tailor-made for gravity rigs that see regular airtime and repeated impacts.
