The Carbon 456 blends years of experience into an unshakeably surefooted, highly responsive carbon frame with massive tyre clearance for top performance in all conditions. It's nice and stiff with just the right amount of compliance, absolutely bomb proof and has the infallable 456 geometry which we all love so much...
The Frame:
New international standards in frame stiffness and strength mean our new Carbon 456 frame had to be subjected to rigorous CEN testing. This involved the frame getting mechanically pushed and pulled horizontally, vertically and through the pedals, plus a variety of impact tests. The Carbon 456 sailed through all the tests.
As a do it all trail centre / all mountain hardtail frame the Carbon 456 is very hard to beat. It's light and extremely fast on climbs, yet well balanced and very easy to control on downhills and technical single track. It doesn't ever feel jumpy although the rear end is re-assuringly stiff. And most importantly it feels like you could drop boulders on it and it wouldn't break.
All of us in the On-One team genuinely like this frame. And as a long travel (up to 160mm) frame that normally builds into a complete bike weight of between 23 and 26lbs it's an absolute steal.
Frames carry our standard 2 year warranty and are new and boxed.

On-One are also known for their excellent range of singlespeed and 29er mountain bikes, carbon and steel rigid forks.
In addition to steel, carbon and titanium mountain bike frames On-One are known for their excellent value range of mountain bike parts and finishing kit. After enjoying success with CNC stems, seatposts and cult MTB saddles they released a legendary line-up of alternative handlebars to critical acclaim. Since then On-One have expanded into custom mountain bike wheels and are developing a range of folding 26" and 29er MTB tyres and clothing too!
