Product details

The Shimano SLX 10-speed RD-M663 guide and tension pulley is an essential accessory for derailleurs, specifically designed for mountain biking. These pulleys are compatible with a variety of Shimano derailleurs, including models RD-5800-SS, RD-M7000-10, and RD-M675. They provide reliable performance and contribute to precise shifting, which is crucial for an optimal riding experience.

The 11 teeth of the bearings allow for smooth and efficient power transfer, which is particularly advantageous in demanding riding conditions. The SLX 10-speed pulleys come in a convenient blister pack for easy handling and installation.
