The Shimano mountain bike gearbox with an excellent quality-price ratio
- VERSATILE AND PERFORMING. This Shimano 12-speed derailleur allows a practical level of adaptability to any type of track.
- SILENT AND RELIABLE. Shadow RD+ technology enables silent transmission and eliminates the risk of chain dropping.
- PRECISE CHANGE. Thanks to the presence of the Hyperglide+ system, the transition from one gear to another is more practical and fluid, but above all stable even on rough terrain.
- IMPROVED EFFICIENCY. Larger 13D pulleys optimize chain efficiency and management for agile, jolt-free shifting.
