OK global bike companies. Here’s the numbers for the best riding trail hardtail around. Get copying now! All geometry listed at ride height with 25-30% fork sag.

Seat tube diameter :: 34.9mm outside (constant), 31.6mm inside (seatpost size).
Headtube :: 1.125in standard external.
Geometry is set for contemporary 140mm travel forks. It will happily take 130′s or 150′s.

So – what’s different? Well, it’s a series of tweaks that I’ve not seen anyone combine in one place before. The 67.5deg head angle is pretty slack by most peoples experiences, but combined with a long top tube and a short stem gives a bike that handles incredibly well at speed, through the rough, yet retains a quickness when you need it. It’s great. We recommend at 50-60mm stem.
Seat angle is steep and gets steeper the bigger the frame. This lets us use a short back end for good stood climbing, but also keeps your weight forward when you’re sat, going up. The steeper seat angle is to stop big lads sitting right back over the back wheel and looping out. It’s the reverse to what normally happens – the other option would be making the rear stays longer on bigger frames, which I didn’t fancy.
Seat tube is reamed for a 31.6mm post – so that you can get a dropper type post in there. It’s noticeable that a bigger post DOES seem to transmit more shock, but if you’re that offended, shim it to 27.2mm. I like to solidity of it, and the Ti back end definitely takes the edge off. Plus get the saddle out of the way when you’re hammering eh!
