Built for adventurous riders who want to tackle any trail and explore the backcountry under their own steam, the Space Chicken is equipped for having fun on the long haul.

Far from a modified road bike, this a ground up gravel bike, with huge tyre clearances letting you run tyres up to 650b x 47c. And of course, those wheels are held in place with thru axles front and rear for security and easy installation.

Gravel specific geometry means youll maintain stability whatever the road surface, but still be in an optimum position to put the power down and the miles in.

The lightweight carbon frameset gives a comfortable ride whatever trail youre on, and has fully capable rack mounts, front and rear mudguard mounts, and a triple set of bottle mounts. Its incredibly capable - this frame can even take 700 x 43c wheels and tyres and even a dropper telescopic seat post. Its future proof!

Groupset: SRAM Force1 HRD is an 11- speed groupset thats packed with advanced off-road features and performance. A single front chainring with 'Narrow-wide' tooth profile and a clutch enabled rear mech deliver amazing chain retention on bumpy trails. SRAMs wide-range 11-42t cassette is combined with a stiff and lightweight 42t carbon fibre chainset to deliver a huge gear for tackling any hill- its what SRAM 1x11 is all about. Powerful, ergonomic Force1 HRD hydraulic brakes complete the groupset giving you huge braking control and effortless stopping power. Force1 HRD 1x11 is our favourite gravel bike groupset.

Wheelset:Hand built by experts, FSAs Afterburner wheelset offers rock solid off-road performance. They are billed as their do-it-all XC-Race-Trail and Adventure wheelset and we can see why. Built on strong and light asymmetrical rims and laced up using straight pull spokes these wheels are light and strong. They spin on fully sealed stainless-steel cartridge bearings and a 6-pawl freehub design.

In the press: Totally Active's Nick Cook reviewed the Space Chicken just after its launch and summed it up by saying "Spinning along a gravel trail it instantly felt at home as if I'd been riding it for years. On more technical trails the Space Chicken was a blast. Climbing was superb, offering more plushness and traction than a regular CX bike but still maintaining that willingness and responsiveness that only the lightest and most XC MTBs can offer."

The Space Chicken Gravel Bike is the perfect blend of all the best bits of every other bike category. It's far more comfortable than a road bike and geared for tackling off-road trails, its less twitchy than a CX bike and comes with all the mounts you'd expect on a real tourer, its lighter and nimbler than an MTB and doesn't have the weight of suspension forks to slow you down. Sourced and built exclusively for us here at Planet X, we offer the best value for money as were cutting out the middleman and dealing directly with you.
