• I ve just built up my bike and the drive mechanism is incredibly loud
    It a 1/8 th chain (i have read they are louder) and 1/8th cog and 1/8th chainring
    what would make it this load?

    1. Not a perfectly straight chainline
    2. Cheap Chain
    3. Too tight
    4. A combination
      any advice on reducing this noise is gratefully received
