I really wanted a wider ratio transmission, and with the One Up 42th cog, on my existing 11-36, plus my 32 chainring....it was perfect! I laughed at all my buddies wasting money on 11 speed set ups.

I like the part, it's perfect.

This thing works great! I have always despised front deraileurs on my mountain bikes. Finally an option that is perfect for me! Thanks for an awesome product! 

perfect alternative to 1x11. love it.

it wont shift perfectly without it

Keep innovating fellas!

I have been running the 42t cog on my DiamondBack Mason for 9 months, it has worked flawlessly, and Im able to climb some trails that were a bit unapproachable on a 36t previously :) I have a 1x10 set up, SRAM parts, 30t RaceFace chainring. Excellent trail/all mountain riding set up.

the rad cage brought saint level shifting back to my extended range cassette. As a pro level racer this truly increased my confidence in race situations
