This helps to provide smoother and more accurate shifting, especially when under heavy loads or while climbing. The 12-speed geometry also allows for optimized gear ratios and more efficient power transfer.

The rear derailleur is made with high-quality materials, including an aluminum outer parallelogram plate and an inner carbon fiber cage. The pulley wheels feature ceramic bearings, which provide smooth and reliable performance. Additionally, the derailleur has a redesigned pulley cage for improved chain retention and better shifting performance.
