On-One Slot Dropout Inbred Frame

Our review

A lively and hugely versatile trail frame that can ride like a top-end steel steed, all for under £200

On-One’s combination of innovative design and giveaway price blew the market apart when their first bikes appeared. This slot dropout evolution of their original Inbred frame is the ultimate high value, high versatility vehicle.


DN6 Lite is a custom butted and custom drawn chromoly tubeset that produces an impressively lively, real steel feel for the price. The long top tube also means you can run a short stem to keep the conventional handling sharp and reactive without cramping your breathing space.

Multiple gussets allow the use of a 130mm-travel (5in) fork – look to the beefed-up On-One 456 if you want to run a longer fork – while the extended seat tube uses a 27.2mm seatpost for extra flex under the saddle.


The multi-part wishbone seatstay bridge and dented chainstays deliver huge mud room around the rear wheel, with outside edge gussets to spread stress. The slotted horizontal axle and chainstay brake mounts allow you to run one or multiple gears, or to change rear geometry too.
