A few words by Colourbolt:
"A collaboration with Moulton, the X-Black is a glorious concoction of their inimitable frame design and our unmistakeable aesthetic.

The X-Black is no normal ColourBolt, but rather a collaboration project with our friends at beloved British builder, Moulton Bicycles. Produced in partnership, using one of their iconic X frames as the basis, but with plenty of our signature hallmarks, this is a model we’re extremely proud of.

Moulton’s iconic X frame was  designed with lightness, stiffness, speed and comfort in mind – perfect for use in an urban life. The angle of the seat tube gives a more relaxed position without heavily compromising efficiency, while the flat bars and higher cockpit encourage riders to sit up and take in the world around them. And then of course there’s the brand’s pioneering suspension system to soften the ride – definitely a first for us.

The frame is painted with our Drenched Black finish, a super-tough industrial powder coat that is designed to withstand virtually anything that can be thrown at a bicycle. Originally conceived as a coating for our winter training bikes, Drenched has a raised, textured effect – which really has to be touched to be appreciated.

The rear of the bike was specially modified for the X-Black with 135mm axle spacing – allowing for the addition of a Chris King single-speed hub. The use of Chris King hubs has been a hallmark of our single-speeds for a while so we were delighted to include one on this build.

The bike rolls on Moulton’s 17” wheels, with Schwalbe Kojak tyres and boasts a black Brooks C15 saddle. The stem is also Moulton’s own design – a unique and tricky-to-perfect wishbone construction built out of stainless steel, and polished to a mirror finish. A Chris King headset adds another premium touch.

The stunning chainring on the X-Black is a Bespoke Chainrings De Luna, with 60 teeth – providing plenty of zip when riding around the city. And of course, there’s a single coloured bolt, the definitive marker of a ColourBolt machine."

The bike can be preordered from our Velorution store.
