I bought a F50 from http://www.thatsdax.com I have a 29" mountain bike with disk breaks and feel good about my first build except for one thing, I am not sure how to count the sprockets. I get 16 on one side for a total of 32 on my wheel. Will the F50 accept this setup or will i have to use a additional bracket for it to work? Thanks. Note: I would still like to keep my current bike setup in case something goes wrong while riding away from home.
