    Pugsley Rohloff Middleburn BB?

    What have, the few, people been using for spindle length on this combo? I'll be using Middleburn square taper RS7 arms with the XC(104) spider on a frame with the same offset as the Pugsley. Usually it looks like a range of 145-155mm, but for a $160-200 BB I'd rather nail it the first time. I know the cartridge can be offset. Probably won't run a bash guard if that helps.

    BB spindle length

    I wrestled with this a bit too. If it's a standard MTB crank (look at the specs for the crank; it should specify a 118mm BB spindle length for a 73mm shell - often written 113/118), then using a 145mm "+5" BB and placing the ring on the outer position of the crank should line up within 1mm of the Rohloff chainline. That's good enough for me, or if you're using a Phil BB you can shift it a bit, or use spacers.

    And, if you're looking for such a BB, PM me; I happen to have one I'd like to sell.
