Only compatible with Shimano 11-42T (M8000) cassettes. For 11-40T cassettes see OneUp 45T Sprocket. Not compatible with SRAM drivetrains.

OneUp Components Shark 50T Sprocket and Cage is part of the widest 11-speed 1X system ever created. A climb crushing, descent hammering, 500% of range. The 50T upgrade increases the stock Shimano 11 speed 11-42 cassette range by 19%. The 50T provides more total cassette range, not just an easier granny gear. Adding the OneUp 50T sprocket lets you increase your 1x11 front chainring from a 30 to 34T without losing any low range.

*Est weight is added weight from upgrade. Total weight of product is ~140g
