Technologies:
- DYNAMIC CHAIN ENGAGEMENT+ - A special tooth profile designed for 1x chainrings, noticeably improving chain engagement for easier pedalling over rough terrain, offering particular advantages in MTB Cross Country, Enduro and Trail riding. Optimized chain guidance also reduces wear regardless of the selected gear.
- HOLLOWTECH II - The core principle of Shimano's Hollowtech II technology is a perfect balance of stiffness, stability, weight and pedalling efficiency. The goal was to create a crank arm that reduces pedalling effort and allows more efficient power transfer. A distinctive forging process enables the production of extremely light crank arms that nevertheless ensure maximum stiffness. The fixed connection of the right crank arm to the bottom bracket axle and its external bearing also contribute to an optimal stiffness-to-weight ratio.
