Hollowtech II spacer placement?
I am converting my Surly Cross Check fixed gear into a touring bike. I have a Shimano 105 triple (FC-5603) crankset which currently has one spacer under the right adapter and none under the left. This gives me a straight chainline for the fixed setup (but with cranks offset from centreline).
The bike is getting 3x9 gears, with a standard 9 speed mountain cassette on a 135mm hub in the rear. The bottom bracket shell width is 68mm. What is the correct bottom bracket spacer configuration in this situation? I've looked through the Shimano documents but they are unhelpful.
