Kitted out with Reverb Stealth routing, 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.

650b Gravel Bike (29er too)

  • SRAM Force HRD
  • Huge mud and tyre clearances
  • Pannier, mudguard and triple bottle mounts
  • Reverb Stealth routing Full Description
  • Description

    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. Swapping between 650b/700c wheels isn't an issue, ride whatever you fancy. With space for 650b tyres up to 48mm, 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.

    Groupset: SRAM Force 1 is a 1x 11 speed groupset that brings a host of great new features to the party. A single front chainring with 'Narrow-wide' tooth profile ensures chain retention. Add in the extra chain tension that comes from the 'clutch mech' design and you have the best chain security you can ride. SRAMs wide-range cassette to give you the maximum gear options for powering up and down the trails, whilst powerful Force 1 HRD hydraulic brakes give effortless stopping power and great modulation so you can finesse your braking efforts to suit the surface conditions. An all-round elite level groupset with significant advantages over its competitors in the field. We've upgraded to SRAM extra wide 11-42 cassette, giving you an even wider gear range than ever before, there's no better bike for tackling the steepest tracks. "

    Wheelset: i25 27.5"" rims with El Guapo hubs are a touch of handbuilt luxury. This 27.5"" wheelset pairs our sensational El Guapo hubs with WTB's sturdy and lightweight i25 rims. It's the best 650b wheelset we've ever made and its hand-assembled here in the Steel City of Sheffield.

    The El Guapo Rattlesnake hubs are still flying under the radar- which is crazy as these hubs use Japanese soucred ABEC bearings, provide tool free dissasembly, weigh less than the new Pro 4 from Hope. Riders tell us the El Guapo sets the new standard for MTB hubs at this price. WTB's i25 rim pairs up a wider 25mm internal profile with a the 27.5"" rim measurement to create a truly stunning rim. Weighing in at only 538g a side the i25 is light and supremely strong for a trail ready rim. We've been loving these rims since day one, they're our favourite UST compliant rim. Laced up with high quality double butted spokes, hand stress relieved and re-tensioned before shipping the EL Guapo i25 wheelset is widely regarded as one of the best value for money wheelsets on the market. if you're looking for a new set of all-mountain wheels and don't want to break the bank to get quality and innovation then you should roll on these beauties."

    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?

    We're only making them in limited numbers. We know the market for such a specialised beast as this probably consists of only a handful of die-hard bike adventurers. But what the hell, you only live once. On-One didn't get famous by following by not taking a few risks.
