After a successful start with their extended-range 1×10 speed kits, OneUp sets their sights on the 1×11 market, offering two products to compliment SRAM’s popular drivetrains.The first is a massive, 44 tooth cog (2 more than SRAM’s standard) and a direct-mount, narrow-wide chainring.


X-Cog 44T Sprocket for XX1/X01

If you spend a lot of time on your 42t sprocket, you’ll probably find that it is wearing out faster than the others. That’s because it is made from aluminum, while the rest of the SRAM X-DOME cassette is steel. The good news is the largest sprocket can be removed and replaced separately from the rest of the cassette, saving you money.

The extra two teeth of the OneUp Components Cog gives rider an lower granny gear without sacrificing top gear speed. This makes it ideal for enduro racers looking to conserve energy between timed runs.

SDM (SRAM Direct Mount) Narrow wide chainrings
