TECHNOLOGIES
DYNAMIC CHAIN ENGAGEMENT+ -The special tooth profile for chainrings of 1-speed drivetrains noticeably improves chain retention, which also makes pedaling easier in rough terrain and offers particular advantages in the MTB application areas of Cross County, Enduro and Trail. The optimized chain guidance also reduces abrasion and wear, regardless of the gear selected.
2-PIECE CRANKSET -The two-piece construction, in which the right-hand crank arm is firmly connected to the shaft of the bottom bracket, serves to optimize the ratio between stiffness and low weight. In combination with the external bearing, which also results in an increased bottom bracket distance, the power transmission is noticeably improved.
