    Once I got the RADr cage, shifting was great and I haven't had any issues with durability.

    Since the 16T was useless for me, the $15 it adds to the price makes it tough. There are less expensive options out there from Wolf Tooth and e*thirteen, just to name two.

    Provides you with a super low gear for 10 speed drivetrains.

    The 16T cog that comes with it was useless for me. Any time I put the slightest amount of power into it, the chain would skip.

    If you have a Shimano derailleur, you really need the RADr cage to make the most of the 42T sprocket.

    Pricey at $90

    The solution of pulling a cog out of the cassette did not feel as good to me as the absolute black option of removing the 11t cog and using a new retaining ring. Compared to the absolute black 40t it fit looser and wore faster.

    Colour choices, cheap, clear instructions

    Fits loose and caused my cassette to explode (xt) Also destroyed freehub(xt)
    The teeth seemed to wear very quickly (I cleaned my chain daily) lasted 4 months of riding.

    I only have one ride with my new OneUp cassette sprocket intalled on my 2012 RIP 9, however, on the first ride it performed excellently. Shifting form the 36 tooth to the 42 tooth
    cog was smooth and almost unnoticeable, even under load. Running the OneUp 42t on a Shimano XT cassette with a 30T Raceface narrow wide chainring. Using a Sram X9 short cage type 2 derailer and having no issue at all. Actually ran with an older non-clutched XT derailer for a few rides, and still didn't have any dropped chains. If you are like me, and trying to get the benefit of 1x11, without the cost, this is a great solution. There are others out with the same solution, OneUp was just able to deliver to me first.

    Ease of setup
    Shifting performance

    Did notice the 15T to 19T jump (missing the 17T) once in awhile. But got used to it.
