50T + 18T SHARK Sprocket and Cage [ 1x11 ]

OneUp your Shimano 11 speed drivetrain with the Shark 50T Sprocket for SLX/XT 11-42 Cassettes.

Only compatible with Shimano 11-42T (M7000/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.

Kit contains: 50T, 18T and Shark Cage 

  • 18T sprocket provides more even cassette progression for smoother cadence and improved shifting

  • Maintains the 42T as the smallest alloy sprocket preventing premature drivetrain wear. No major drivetrain manufacturer goes smaller than 40T in alloy.
