Ultra-Shift Teeth Design means 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 -- it's fast, accurate and quiet, even under stress
Reinforced mounts for second and third triplets offer greater sprocket set rigidity, performance and precision
Steel construction with nickel-chrome surface treatment reduces chain/sprocket friction and extends sprocket life
Light alloy lockring for weight savings
