OneUp Cassette Expander 44T Cog Kit
Extend the life and range of your 10-42T cassette by replacing the aluminium 42T with the X-cog 44T sprocket. If you spend a lot of time in the 42T Cog it can wear out the Aluminum sprocket faster than the rest of their steel cassette. Instead of throwing tossing a $400 cassette that's mostly still good, slap on the new 44T and get rolling again for much less. The X-Cog provides more range, not just an easier granny gear. The increased range is a must for enduro and stage racers. Maximize the chainring size for timed downhill sections, while still being able to conserve energy on transition stage climbs.
- Compatible with: SRAM XX1 and X01 (Not compatible with X1 or GX fully pinned cassettes)
- 8 optimized upshift points
- Press fit design ensure ease of assembly (no loose spacers)
- Full spline width prevents gouging damage to freehub
- Sprocket material: 7075-T6 Aluminum
- Sprocket weight: 100g (44T)
- OneUp adapted cassette weight increase: 15g
- Cassette range improvement: 4.8%
- Colors: Black, Green
Just in time for my trip to Cali where there are 3-5000 feet climbs where my legs won't be use to. So to save my legs I will run my 30T and this 44T to make life a bit easier when riding out there. Once I head back to my local trails I will run a 32T front. The ratio will be similar to running a 30T-42.
Install was cake, I used a big set of pliers to press them in together, otherwise very straightforward.
