About the On-One brand.

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.

Sizing Guide

As our frame geometry is COMPACT you need to knock 3cm off “conventional” frame sizes. If you want a longer frame, you can go up a frame size without ruining yourself on the top tube.

Rider Height Suggested Frame Size
5′1″ to 5′6″ (155-167cm) S (48cm)
5′5″ to 5′10″ (165-178cm) M (51cm)
5′9″ to 6′1″ (175-185cm) L (54cm)
6′ to 6′4″ (183-193cm) XL (57cm)

Sizing Notes

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 also depend on a rider’s torso and limb length.
