Just got a Raceface Turbine LP crank (26-36-48) with ISIS bottom bracket to put on my touring bike.
The rear spacing is for 130mm hubs. The shop sold me a bottom bracket with 113mm spacing. The bottom
bracket instructions say the ideal chainline for this equipment is 48.5 to 49.5mm.
I measured the existing chainline before taking apart the bike, and found it to be about 46mm (to
the center of middle chainring). Was this bottom bracket sold to me thinking that I had a 135mm rear
spaced setup? Would a 108mm bottom bracket work better for my setup?
