An appearance with Dave Haygarth at the Three Peaks Cyclocross and the following review on Cross Junkie suggest that the 'Disco is headed for great heights:
"... light, very stiff and comfortable to carry... race performance oriented but with perfectly adequate clearances for a modern cross frame. A potential mud-fest at Brockholes, Windermere will test this properly, but the Disco passed the Horwich Humdinger slopfest test easily, lasting the whole muddy race with barely any buildup of mud, and arguably less than other canti equipped bikes around it"
"...the whole package just gels. That is not to say that the Disco doesn't climb like a rocket- it does. Nor that it doesn't track in corners like it's on rails- it does. Nor even that it is vague and skittish in technical descents- because it is anything but. It just simply comes together in one complete package that lets you get on with the riding, fast or slow, dry or muddy and does not intrude in any way at all"
Much more versatile than exclusively a cyclocross race frame, the Dirty Disco is also perfect for a huge range of applications including commuting and touring.

On-One is an independent British manufacturer of bikes and cycle components based in Yorkshire, UK.
Known originally for classic, award winning steel frames - such as the On-One Inbred, On-One Pompino fixie and On-One 456 hardcore hardtail - On-One have continually embraced modern manufacturing materials with the Carbon Whippet, Scandal and the world's first long travel carbon hardtail, the Carbon 456. 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!
On-One's aim is to offer high-spec mountain, commuter and fixie bikes direct to the consumer, cutting out the middleman and slashing prices to the absolute minimum. They've been at the cutting edge of the British mountain bike scene for years and are now branching further afield with new international websites opening across the world.

All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.
Correct frame size choice can vary greatly with riders' torso length. If you have longer legs and a shorter torso, go for a slightly shorter stem. If you think you are borderline between sizes, and you have longer legs and a shorter torso, go for the smaller frame size. If you have shorter legs and a longer torso, go for the larger frame size to get the extra top tube length.
As the frame sizes increase, so does the length of the head tube. If you are inflexible or perhaps have a history of back problems, consider going for a larger frame size. This will increase the relative height of the handlebars making the position less “extreme”. The larger frame will also have a longer top tube, so you’ll need to compensate for this with a shorter stem.
