MRP

2x Chain Retention System 39/42t

MRP spent just about two years designing this chainguide to be the ideal solution for chain retention on mountain double cranksets. Working closely with SRAM (who was at the forefront of popularizing 2x MTB drivetrains) they settled on a two pulley design that's whisper quiet and keeps your chain on the rings through rough shifts and backpedaling. They integrated a partial bash guard on the bottom that puts bash protection only where it''s needed to reduce weight from full-ring designs and it has a plate that extends up and prevents the chain from dropping on the inside of the small ring. MRP''s 2x is a lightweight, integrated solution for double ring drivetrain management.
