Oneup Components Shimano 47T Expander

Do you find yourself in the midst of a killer steep climb, and you're pushing on the thumb paddle of your rear shifter searching for one more gear only to find that you've already maxed out? Just one more lower gear could be the difference between pedaling to the top or having to shamefully dismount and push your bike to the peak. Oneup doesn't want you to experience such shame. They know the limitations of stock gearing and provide solutions for every rider, and every condition. You can Oneup your current Shimano 11 speed drivetrain with the 47T sprocket for SLX/XT (M7000/M8000) 11-42T cassettes. Why bother when Shimano make an 11-46T cassette? The 11-46T has a huge, clunky 9T jump from 37-46T meaning that the shift to the biggest sprocket feels like a shifting into a granny ring. Adding Oneup's 47T sprocket to the Shimano 11-42T cassette gives you 5T jumps in the bigger sprockets - 37-42-47T - making the lower gears extremely useable. The 47T requires no derailleur cage modifications, so it's a quick and easy install.
