ULTRA-SHIFT TEETH DESIGN
Every sprocket tooth is designed and placed to perform a specific function, such as raising or lowering the chain or giving maximum power transmission to the wheel.
ULTRA-SHIFT SYNCHRONIZATION
Sprocket tuning allows for maximum shifting performance without hesitation : fast, accurate, and quiet, even under stress.
REINFORCED MOUNTS FOR SECOND AND THIRD TRIPLETS
Greater sprocket set rigidity - performance, precision.
NICKEL-CHROME SURFACE TREATMENT
Reduces chain/sprocket friction - extends sprocket life
