Oneup Components Shark 50T Expander Kit

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.

Oneup 50 Tooth Shark Kit Specifications:

  • Contents: 50 and 18T cogs, longer Shark derailleur cage
  • New cassette progression: 15-18-21-24-28-32-37-42-50
  • Materials: 7075-T6 Aluminum (50T and Cage), Nickel plated hardened steel (18T)
  • Compatibility: XT M8000 11-42T cassettes (For Shimano 11-40 use the OneUp 45T sprocket), Cage compatible with M9000/M8000 derailleurs (GS & SGS)
  • Weight: Cassette upgrade 80 grams, RD upgrade 9 grams
  • Please note: In our testing we have found that owners of e*13's wide flange hubs such as LG1, TRS and TRS+ will not be able to install this kit due to interference with the hub shell.

Built at eagle equivalent drive train
I love my new drive train. Built an eagle equivalent drive train with a 34 ring up front. I wanted to achieve a similar range as the 2x 11 I was replacing. Having the ability to spin up climbs rather than strain was achieved with this kit.

Poor quality
18t cog worned out after 2 months. Dont really worth the expense. Better to go with the native 11-50 sunrace.

Great engineering
No problem with delivery, but it is a bit on the long side compared to some other on line sellers.

pedro on Apr 13, 2017
BEST ANSWER: if he refers to box brand it can't be use,but if he refers to shimano cassette of 46t, I don't see the reason to use it,because there are only 4t of difference between them.

on this drivetrain.
