I took apart my ISIS crank and bottom bracket on my Surly 1x1 for cleaning today. When reassembling, I looked up the torque spec for the ISIS crank bolt and it said to bottom it out (30 to 50 ft-lbs). I did this on the drive side and the crank began rubbing on the bottom bracket (where the 20 tooth splines are on the cup). Do I have a mismatched crank and bottom bracket? --- Crankset is RaceFace Prodigy XC and bottom bracket is RaceFace SRX 108mm.
