On-One 456 Frame
On-One 456 classic steel long-travel freeride hardtail. Created from a desire for a bike to be a hooligan on yet still be rideable uphill. Run 4, 5 or 6in travel fork. Ride all day. Ride any terrain.
Frames are hand TIG welded out of "DN6 Chromoly"- our name (it's a long story) for double butted 4130 cro-mo steel tubing. The top tube is the same size (and wall thickness, and material spec) as the downtube. A 35mm tube, 0.9mm at the ends and 0.6mm in the middle. Compared to the 28.6mm top tube on the standard inbred it's 50g heavier, but about 40% stiffer and 60% stronger in frontal impact. Which is what you want when you're ploughing through things.
That means the whole front end is just a whole heap more solid, and the fact that the two tubes are identically sized means they take the loads a lot more equally, strengthening things further.
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!
