The Cage Guard is designed to add a layer of protection to your derailleur pulley cage to help prevent costly damage caused by rocks and debris. By limiting impact damage, the Cage Guard helps maintain smooth shifting performance and keeps your high-end derailleur in top condition.
Precision-machined in MRP’s Colorado factory, the Cage Guard is made from durable, low-friction Delrin thermoplastic, designed to withstand normal impacts and glide over rocks.
