OneUp 50 Tooth Shark Kit

OneUp's 50 Tooth Shark Kit is part of the widest 11-speed 1X system ever created. When paired with a Shimano 11-42T (M8000) cassette (SRAM systems will not work with this), the sprocket will produce a 500% range. Ideally, you'd up your front from a 30 to a 34T ring, and have overall more total cassette range. With your purchase, you get the ring and new cage for your existing derailleur. The cage is compatible with M9000/M8000 derailleurs (GS & SGS). You also get a new 18T cog to replace your existing 17T and 19th tooth sprockets.

  • Contents: 50 and 18T cogs, longer Shark derailleur cage
  • New cassette progression: 15-18-21-24-28-32-37-42-50
