    Recently converted by TSR 27 to a TSR 9 (rebuilt a wheel and used the SRAM 9 speed cassette that came with the SRAM dual drive). It had a 44T crank fitted but needed to upgrade to stock Sturmey Archer 55T crankset that is fitted to TSR 9s. At the moment the BB is a 68 x 111mm made by sunrace which I think is the one that comes fitted stock by Pashley on the TSR 27.

    However the new crankset has two guards and the inner one just touches the frame. I think a 68 x 113mm will do the job and hopefully the chain line will be ok 🙁

    In the end I used a spacer on the right hand side to move the main crank out a little.

    TSR9 Chainwwheel, 54T or 55T? A minor point, the Sturmey Archer chainwheel for the TSR9 I think it is 54T.

    Typo, as you say its 54T
