MRP 2X 34-38T BLACK ISCG

The MRP 2X 34-38T Black ISCG (Part Number: CR7750) is a shiftable dual-ring chain guide engineered specifically for mountain bikes using a 2x drivetrain layout. This variation features the original ISCG (Old / 03) mounting standard, making it ideal for older frame designs or specific boutique frames that do not use the wider ISCG-05 tab pattern. 

Shiftable chain guide for SRAM and Shimano 2x drivetrains.
