Contrary to the launch marketing of SRAM’s T-Type Transmission rear derailleur, only the hanger interface is virtually indestructible; the derailleur cage and pulley is susceptible to trail damage. MRP’s Cage Guard is designed to protect your Transmission derailleur pulley cage from costly damage caused by rocks and debris.

The Cage Guard is precision-machined in MRP’s Colorado factory from low-friction Delrin thermoplastic, designed to withstand impacts and glide over rocks. The 8 gram, $29.95 Cage Guard adds piece of mind. See more at MRP.
