Tricky – it was a Large. I had about a couple of mm gap between the bottom of the reverb nut and the collar. Perfectly fine but I think i’d probably err on the side of a medium if I was going to buy one. The bike fit fine other than that – reach wasn’t too much at all with a short 30 – 35mm stem. It was a lovely ride.
Also I would probably run a longer travel fork too, the BB was very low and I was getting alot of heavy pedal strikes. It was on plus wheels so a 150mm fork, and i’d go for a 29er with a 150mm fork cashing in the extra 10mm fork length and the larger diameter of the wheels to reduce pedal strikes.
