It's been a funny one this. It very nearly existed about five years ago when I was designing the Planet X Compo - which was a sort of "cult hit" - ie: some people loved it, but sales didn't really set the world alight... I wanted to make it in steel, as it was around the same time on-one started, but lots of people I spoke to worried about weight, and flexyness (in a bad way), so we went with Easton RAD, and it was great - but really expensive, £500 for a frame, and it, well, never really flew. Climbed great though.
You'll need a seatclamp - the seat tube is 29.8mm outside diameter at the top, but clamps labelled 30mm will be fine too. The seat tube butts down to 28.6mm outside at the bottom, for your front mech, and inside the frame takes a 27.2mm seatpost. BB is 68mm shell. Front mech is top pull. Brakes are international standard. Headset is inch and an eighth. All the bits off a standard inbred will fit.
Geometry
Angles alter by about 1deg per inch of fork travel. So with a 4in fork, things go to 70.5deg head, and 74 seat, and with a 6in fork, back the other way to 68.5deg head and 72deg seat. The point of all this though is that at full compression, all forks are the same length, and if our geometry means it doesn't get stupid and squirrely when you're all bottomed out (the last thing you want really). Our 16.75in rear stays keep mean there's a touch less weight on the rear wheel on steep climbs, which translates to more weight on the front wheel. Longer chainstays help you keep a better line on climbs. And our huge tyre clearance lets you run bigger tyres if you're worried about traction!

What's it made from?
456 frames are hand TIG welded out of "DN6 Chromoly" - our name (it's a long story) for double butted 4130 chromoly tubing.
