The Space Chicken is On-One's unique Gravel bike, a versatile big wheeler that can run 700c or 650b wheels with grippy tyres. Kitted out with Reverb Stealth routeing, thru-axle dropouts and built to take a single front ring between 28-42 it's part gravel bike, part tourer, part cyclocross and all fun. It's a true monster.
While the Space Chicken's name might not make any sense everything else about it makes perfect sense. Built for adventurous riders who want to tackle any trail and explore the backcountry under their own steam the Space Chicken is equipped for the long haul. Handbuilt from IM carbon it's surprisingly lightweight, especially if you're coming from steel or titanium frames.
With thru axles, disk brakes, Stealth Dropper routeing, internal cable routeing, 3 bottle mounts, rear pannier mounts and space for full mudguards we've included all the details that any adventurer could need. What you don't see on the inside is just as important as what's on the outside and that's why you'll find extra layers of carbon on the seat-tube and top-tube to help support the weight of your bikepacks. An extra bottle cage on the downtube helps you carry enough liquid for the long haul.
The Space Chicken's versatility works hand in hand with our carefully developed frame geometry. Choosing between 650b/700c isn't an issue, ride whatever you fancy. With space for 650b tyres up to 47mm, you can choose wheels to match the conditions. We've included a dropped RHS chainstay to help clear wider tyres and offer more space for bigger chainrings. Whether you're a beast looking to run a 42t front ring for fast CX riding or a serious diesel engine who'll grind out the miles with fully loaded panniers and bikepacks on a 28t the Space Chicken is for you.
Gravel, touring, cyclocross, big wheels, big tyres, huge load carrying ability, built for 1X drivetrains, dropper seat post ready and kitted with flat mount disk brakes the Space Chicken is ready for anything- are you?
