SUNRACE cassette CSMZ903 11-51 teeth | 12-speed silver
Light but inexpensive 12-speed alternative from SUNRACE for Shimano drives. It is compatible with the current 10/ 11-speed MTB freewheels from Shimano and SRAM and has a gradation of 11-51 teeth, which corresponds to a bandwidth of 464%. The optimized tooth shape in the Fluid Drive Plus design improves the gear changing phases and ensures smoothness even under load. It is therefore unrestrictedly suitable for uphill slopes. Aluminum is used for the top 3 pinions of 39-51 teeth. The remaining smaller pinions are made of steel. Light, red anodized aluminum spiders not only reduce the weight but also ensure a beautiful look.
