In Mountain bike riding, trail conditions change drastically from one second to the next, from one turn to the next.

Features:

• Special gear teeth function: shimano’s dynamic chain engagement+ is a special gear teeth profile designed for use in single-chainring configurations for xc, enduro, and trail riding.
