Tried a Tiagra Triple crankset but, allthough the arm cleared the chainstays, the chainline was 52mm with a Wolftooth ring. Ordered a Sora double just to check; with the chainring spaced out 3mm this will give 49mm chainline, clears the chain-stays, and has 150mm q-factor. Sora crank with 44t Wolftooth chainring weighs 800g.
Next step: deciding if I'm going for Ultegra or Ultegra Di2...
