Extended tooth design.

Our extended tooth was developed before Shimano, it was meant for 17T at first, with some changes and improvements, we applied extended tooth to 11T. it makes shifting faster, and chain more stable. Works best in pairs. 

The design of the deep tooth guide wheel significantly improves the shifting speed of the transmission, and there is no abnormal sound during the shifting process, which better prevents the chain from falling off.
