Moulton x ColourBolt Black

Two British brands – Moulton and ColourBolt – have combined their efforts to produce this stunning new luxury single-speed. It’s based on Moulton’s iconic X frame design, and has been enriched with one of ColourBolt’s signature paint finishes. The frame has engineered 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.


The frame is painted with ColourBolt’s exclusive 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 their winter training bikes, the ‘Drenched’ finish 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 ColourBolt single-speeds for a while, and is another instance of the two brands combining their distinctive personalities.

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.
