    One9 BB

    Hello One9 owners, quick question about the Bottom Bracket. Do you need one spacer on drive side of BB.

    Thanks, Do you have any tips on setup or a good starting point for the cranks vs the size of cog? My thought is to start with the largest cog and the ebb towards the rear and as you go smaller in cogs, you would then rotate the ebb forward. Does this sound right? How many chains do you use between 19t and 22t cogs.

    Rotating EBB clockwise puts slack into the chain.

    Try a 32 x 20T to start with, especially if it's your first single speed. That ratio was good for me first season running 175mm cranks.

    I usually run a 19T and never bigger than 20T so cannot tell you how much chain you will need for a 22T

    Depends on which side of the bike you are on.
