On-One Pompetamine Cro-Mo Urban Frame
On-One Pompetamine Steel Urban Frame.
The Pompino's newest cousin takes 700c wheels, disc brakes and is compatible with Shimano Alfine hub gears for the ultimate commuter / touring / do it all bike.
The Pompetamine features greater tyre clearance so you can fit up to 35mm 'cross' tyres, plus the disc brake mounts are on the inside of the chainstay for clean looks and the option to add panniers.
Perfect for zero-maintenance commuting, you can fit an Alfine hub or a 135mm fixie or single speed hub.
And it looks nice too...
- Compatible with matching disc forks
- 135mm rear spaced drop-outs
- I.S disc mounts
- Cable routing for disc brakes and hub gears
- Frame weight 2200g
- Available in retro white and "that blue"
- Glow in the dark white available for a limited time only!
- 35mm max tyre clearance- Centrelock disc wheels are recomennded for maximum fork clearance.
Note- Glow in the Dark white does glow really well but is slightly off white in daylight. Somewhere between white and caramel.
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.

| Rider Height | Suggested Frame Size |
|---|---|

| 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.
