Due to popular demand we are proud to introduce a drop bar version of the On-One Pompetamine- our disc only steel framed multi-purpose hybrid.
Versa VRS-8 drop bar shifters are a perfect match for Shimano's renowned 8 speed Alfine hub gear system, offering unmatched low maintenance performance and a gearing range nearly as wide as conventional derailleur systems.
Breaking new ground in cross over bike speed and versatility the drop bar Pompetamine bikes are fast, reliable and tough enough to take a right hammering- whether that be on rough city streets, canal towpaths, bridle-ways, touring, expeditions or even cyclocross (now UCI are allowing disc breaks these bikes are competition legal).
The On-One Pompetamine Versa ticks the boxes of speed, comfort and versatility with confidence. Specified to a high level throughout and offering full customisation included in the price, it's a total Cycle to Work bargain!

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.
