OneUp Components is small outfit based out of Squamish BC that’s become known for creating products we wish other companies had made.
Case in point: Expanded rang one-by drivetrains. We’ve had a lot of success with their wide range conversion for 10 speed drivetrains as detailed in this post. This year we’ve begrudgingly moved on to 11 speed drive trains but they work pretty damn well. Unsurprisingly, a drive train designed for an extended range works better than a modified one.
That said, we’re doing bigger rides and with more elevation, the setup that was awesome on local flow trails is a bitch to push on burly all day trail missions.
Option 1: go back to a double. (no thanks)
Option 2: run a really low front ring and get used to spinning out quickly on descents.
Option #3: Shark Up.
You’re looking at the Shark Sprocket, OneUp’s new wider range solution for those running Shimano 11 speed drive trains. Boosting a 50t low, it’s designed for use with the Shimano 11 speed XT 11-42 cassette. Also included in the kit is the Shark Cage, which is compatible with M9000/M8000 GS and SGS (mid and long cage) derailleurs, which adds 50% more pulley offset. Also included: an 18t cog to keep the cassette progression smooth.
But wait — there’s an option #4 too.
Want to increase that range on that non-SRAM freehub even further? (Eagle who?) OneUp has that covered too. Partnered up with Hope, they’ve develop a non-proprietary freehub body standard that accepts a 10t sprocket. The MiniDriver Freehub will run you $40.00, and the Shark 10t Cluster another $45.00.
Combine it with the Shark tooth sprocket system and you have a ridiculously wide range of gearing while staying team Shimano. Or simply gear down to a 28t oval ring up front and add the 10t to have one more gear before spinning out.
I’ve been running a 32 oval and while it’s worked quite well, I’m about to go way lower, and the minidriver has my name all over it. Soon as I buy a hub that works with it at least.
In addition to the impression collection of drive train options, OneUp now offers a number of chain retention solutions that offer security with a minimal weight penalty.
