I did wonder about that but would like to try to avoid extra expense if possible, and although using it as a single speed at the moment, I was quite looking forward to trying the fixed side soon too.
I've just taken a look at Sheldon Browns website and read these two paras that might help:
Bottom Bracket Spacer:
If you need to increase the chainline (move the chainring to the right) you can usually add a spacer washer between the right-side bottom bracket mounting ring (or cup) and the bottom bracket shell of the frame. The usual spacer for this is a Sturmey-Archer sprocket spacer. Metal spacers without internal lugs used with Shimano cassettes also will work. These fit all threaded bottom brackets except Italian size. Sorry, I don't know of any source for a spacer that will fit an Italian (36 mm) bottom bracket. Adding a spacer on the right side will move the left bottom bracket cup or mounting ring inward -- a lockring might not then engage enough threads, so check before you commit to this.
Change the Bottom Bracket
......With steel frames, it used to be common to add a bit of clearance for the small inner chainring of a triple crankset by a light hammer blow to the right chainstay, using a broom handle to soften and spread the impact. Only do this with a steel frame!
Would I be right in thinking a spacer (1.6mm and only 99p) will still knock the chainline out and therefore not be a great solution for my rear wheel? Also, I don't know if that would work with the threadless hub I'm using - I assume it would, since it would be pulled into place with everything else when tightened up.
I've already spent more than I should (read as 'was allowed by my OH'), and we're now expecting, so pennies saved on the bike score me big brownie points now that I feel I will be needing in about 6 months time! ;)
