With SRAM's recent announcement that the front derailleur is dead in the world of mountain biking, it seems only appropriate to follow-up with news of yet a wider option 1x option. Meet the new OneUp Components Shark 10-50t set-up, which it's calling the widest range 11-speed 1x system ever thanks to a whopping 500% gear range.

The OneUp Shark is a set of modular upgrades for Shimano 11-speed mountain bike cassettes that extends the range of a stock 11-42t cassette by nearly a third with the addition of a 50t sprocket and cage kit, a 10t cluster, or both. The idea is that you can build the ideal cassette for your trails and abilities. The converted 11-50t cassette is the widest range available that uses a standard freehub body, says OneUp.

At the other end of the spectrum, if you are looking to add more top end gearing, OneUp is offering its new Shark 10-12t cluster and OneUp mini-driver. This adds 10% of range on an 11-speed Shimano mountain cassette. OneUp collaborated with Hope Technology to develop this 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 Swiss hubs with more coming soon, says OneUp. Because the mini-driver open standard is not guarded by patents, production of inexpensive 10t equipped cassettes is possible.

The 10-12t cluster and mini-driver is compatible with Shimano 11-speed 11-40 and 11-42, and OneUp'd Shimano 11-45, 11-50.
