MRP SXg SL Chain Guide ISCG05, 30-34T

The SXg features upper and lower chain retention, as well as burly bash protection. Completely silent and efficient, the upper and lower guides are easily setup for zero rubbing and, with no moving parts, introduce zero drag into your drivetrain. Fiber-infused bash protection lets you charge through rock gardens without a care in the world. When taking the fastest or gnarliest lines are the only things that matter, no other guide can compete.
