On-One CNC Anodized Swap-Out

On-One CNC Anodized Swapout

Replacement drop outs for all On-One frames that use the 'Swapout' system. Choose single speed slot drop out or vertical drop outs for geared bikes.

A revolutionary system which mounts the brake caliper inside the rear triangle, shielding it from knocks and allowing the use of a standard rear pannier rack. CNC machined and anodized these are the new versions of our ground breaking swap-out system.

Note: "On-One Swapout Replaceable Dropout / B2 / Geared / Disc Side Outer" is specially designed for frames where brake caliper clearance is an issue by mounting the caliper on the outside of the rear triangle as in conventional systems. Contact our technical team if you are unsure.

Not supplied with bolts- these come with the frame or are available separately.

Weight: 150g per pair including bolts
  • CNC machined
  • Anodized finish
  • Available in 4 colourways
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.
