I’ve got a 2014 model. Size medium and I’m 5″10″ with 32″ inside leg. I find the sizing spot on.
Right now it’s setup for winter riding with Spesh Storm Control tyres. In the summer I run a 2.35 Hans Dampf on the fronts, setup tubeless at a low-ish pressure it takes a lot of the harshness out of the front rigid fork. I run a 2.2 Racing Ralph on the rear in summer and this combination seems to work well (for me anyway).
I swapped out the standard, own brand brakes for XT after one ride. I also changed the cranks as I had some spare Middleburn Unos in the shed. Since then II’ve also changed the bars to Rethall Fat Bar Lites. Other than that it’s all standard 😉
Overall, great bike for the money and worthy of the odd upgrade.
