DSS4 RACE READY STEEL - Frame set from £2245


You remember that scene from Days of Thunder where Harry’s building Cole’s race car? Well that’s what its like every time we build one of these! The DSS4 uses the most advanced steel tubing, the worlds finest frame finishing components and the excellent Columbus Futura fork. Building into an extremely capable steel race machine, ready to thrash it out at the pointy end of any race.

The bike has been race tested under the legs of Kibosh Racing, grabbing wins and podiums, with team members wowing spectators with the bikes incredible handling. Here’s what Josh Greet, Kibosh Racing Chief had to say about his own DSS4 machine:

“I am cornering twice as fast as I used to with the bike giving me a shit tonne of confidence. It feels so planted at all times. No skipping rear end whilst sprinting, just going forward very quickly.”

I think “twice as fast” may be a slight exaggeration, but you get where he’s going!


The frame is based around the incredible Columbus HSS tube set, Columbus’s ultra modern, hydro formed, oversized tubing. It builds into a stiff, direct frame, but never loses that steel feel and the confidence that brings. Something that will gain you many more seconds than simply counting grams.

Featuring an oversized opposed oval down tube, a heavily ovalized top tube and beautifully smoothed in wide set seat stays, putting stiffness where it’s needed. It makes an ultra modern frame, all with that feel of a finely tuned steel machine.

Chemically treated internally and finished with silver brazed, stainless steel braze on’s and bosses, including dead ended bottle bosses. These hidden details make sure your frame is ready to go season after season…

We love paint and for the DSS bikes you have several options:

Single Colour – If you like it simple you can choose from any of our base colours for a single colour with logo’s design.

Signature – The DSS4 Signature paint is simple and striking. It gets the brutal black wrap top tube (see below), letting everybody know on the start line, this bike doesn’t take no S*%t.

Custom Signature – Much like with the Kibosh racing colours taking inspiration from none other than James Hunt’s Marlboro Mclaren. We offer a special Custom Signature option on the DSS4. Let us know your favourite team and era from the golden days of motor racing and we’ll cook you up something to add few more mph to your ride!


We can offer a selection of custom upgrades to tune the bike to your exacting requirements.
