Orbis +

Gravel or tarmac, the choice is yours

Why not both

The best of both worlds. Road and gravel. While the Orbis is a pure sealed road machine, Orbis + is the split personality. Hitting the end of that sealed road, only now pushing on and discovering where the gravel continuation actually ends. Taking the latest – wider – rims, we designed the Orbis + around the demand for a platform that would allow for bigger tyres while still maintaining the soul of a road bike. 


A semi-integrated headtube and Enve road disc fork compliments the flat mount disc brake and formed chainstays. All still built around a road groupset. Wider bars and a shorter reach help provide greater control and tyres up to 40mm (measured) ensure you have all the grip you need. The term “quiver killer” is cliche…except that this truly is a ‘do it all‘ bike. The Plus is made to be just as at home with our carbon fenders as it is peeling turns in the local bunch ride. The only issue is what to do with all the other bikes it just made redundant.

Orbis + Yoke

3D printed yoke

Allowing up to 40mm tyre clearance on regular road chainrings, this is the big tyre clearance you need without sacrificing any of the stiffness.

3d printed cable inlet

With gear cables are now electrical (or non-existent) and brakes now a hydro line, we felt the time was nigh to take that clean look a step further and fully internalise the cables. Only to do that we needed an inlet for the tube. So we 3D printed it. In titanium. You’re welcome.

Orbis + Guard Rear Wheel

Mudguard mounting front and rear

All business during the week but play the rest of the time. Orbis+ allows you (and your riding buddies) to stay dry for those more relaxed spins. But slip the fenders off when a fondo or race day rolls around. Did we mention they come in carbon too? So light you won’t even feel them.

Orbis + Geometry

Road geometry for gravel. An extended wheelbase with a lower bottom bracket is engineered for larger tyre clearance and less chance of (resultant) toe overlap. Higher front ends with a slightly shorter stem and wider bars are all part of the front end changes from an Orbis that ensures handling with a larger tyre remains responsive. While you could run a tyre less than 32mm, the geo is optimised for that 32-40mm range.
