OneUp developed the Switch system to reduce the cost of replacement chainrings, increase compatibility with new offsets, and to make the process of changing your chainring much faster and simpler. Rings can be replaced in less than a minute with only a 4mm allen key, without removing your crank. Simply loosen the bolts 2 turns, unlock the ring by rotating it by 20 degrees, and pull it over and off your crank. Reverse these steps to install your new ring. If you plan to ride a trail that you know is steeper than your local trails, you can switch to a smaller ring in the parking lot, in less time than it takes your friend to put on his riding shoes!
This kit includes the Switch Oval chainring and Non-Boost Cinch carrier, which has a 6mm offset that will achieve proper chainline on most Non-Boost/12x142mm bikes. The carrier mounts directly to Race Face Cinch compatible cranks.
