Selecting your crankset is very important to make your 1x9 function correctly without making the whole process of building a 1x9 overwheling. Raceface X-Drive and X-Type cranksets ulitilize spacers to properly position the chainline.Setting up a 29er to run as a 1x9 is a little different than a traditional geared 29er bike. First off you need to find a good chain guide. I would start off with a MRP 1.X Guide. The MRP 1.X is guide that mounts to the BB and in available in two different sizes; 32-36T and 32-40T.

Bash Guards:
Chain Sizing can be done with warping the Big Cog and Chain ring (Big or the only Chain ring)and then add 2 links. You may have to fine tine if your bike is a full suspension to make sure that in full travel there is enough chain. Closing thoughts.
