I know where the pre-loaded shock adjustment tool should be located on the bike(under the rear seat) and its not there and the previous owner didn't have it either so i have to get a new one. i know how it works and such but the only question i have is
Where can i buy the shock adjustment tool...
You can probably make this at home, to check the alignment of your chain and sprocket. It's basically a bracket that goes onto your rear sprocket then a long thin rod as a reference line to see if your chain is properly aligned.
