A climb crushing, descent hammering, 500% of range.
OneUp Shark is a set of modular upgrades for Shimano 11 speed mountain cassettes. Extend the range of your stock Shimano 11-42T cassette by almost a third, by adding a 50T sprocket and cage kit, a 10T cluster or both. Shark allows you to build the perfect cassette for the trails that you ride.
Shark 50T Sprocket and Cage Kit
Increase your chainring size by 4 teeth, and still gain range on both ends of your cassette. This means a higher top speed, a better average chainline (you now spend more time in the middle of your cassette) and legs for days on your next backcountry epic. The converted 11-50T cassette is the widest range cassette available that uses a standard freehub body.
Shark 50T Sprocket Tech Specs:
Cassette Progression: 11,13,15,18,21,24,28,32,37,42,50
Sprocket Material: 7075-T6 Aluminum (50T), Nickel plated hardened steel (18T). Maintains the 42T as the smallest aluminum sprocket, preventing premature drivetrain wear. No major drivetrain manufacturer goes smaller than a 40T cassette sprocket in aluminum.
Compatibility: XT M8000 11-42T cassettes (For Shimano 11-40 use the OneUp 45T sprocket)
Freehub requirement: Standard freehub
Cassette range improvement: 19%
Colours: Grey or Green
Shark Cage Tech Specs:
Pulley Offset: 50% more than stock
Compatibility: Shimano Shadow+ 11spd rear derailleurs
Colours: Grey or Grey/Green
Shark 50T Sprocket and Cage Kit MSRP: $125 USD
Looking for even more top end? Add the Shark 10-12T Cluster and OneUp MiniDriver, to gain another 10% range on any 11-speed Shimano mountain cassette.
OneUp has collaborated with Hope Technology to develop a non-proprietary, freehub body standard that accepts a 10T sprocket. This shortened version of a standard freehub is available for Hope, Stan's and DT hubs with more coming soon. The MiniDriver open standard isn't shrouded in patents, making the production of inexpensive 10T equipped cassettes a future possibility.
