Bottom bracket is 118/73. If they did a longer axle I’ve not seen one. It’s marked 68 etype, 73 std no spacer. I tried a 2.5mm spacer and whilst there’s more clearance, the nds cup has to screw in a long way to support the nds bearing. Everything should fit fine, chainring to centre is on spec. It’s just odd how the chainstay curves out towards the crank arm where it joins the cast yoke.
