Regarding the shifting performance, we specially designed the tooth profile and used narrow teeth to prevent the chain from falling when stepping backwards.

Accurate pedal lap speed control makes the closing ratio transmission device more efficient use of energy, and can be easily installed without changing the rear derailleur;

From beginners to professionals are perfectly adapted to the style of each cyclist to ensure the best performance.
