Ultravox - the frame
The frame carries the characteristic Swift look of a meaty squared downtube and angular finer features. What first struck me about this bike was the leaf-like seat stays meeting in a blade of carbon at the rear brake mount. In contrast, the headtube, downtube, bottom bracket, and chainstays are almost oversized providing the Ultravox with a super sturdy base infrastructure.
Thanks to internal routing the clean lines and finer details of the design aren’t interrupted by a nest of cables. A cable management box is located beneath the bottom bracket to ease the task of internal routing which can be a bit of a pain for those wielding a wrench. The Ultravox is also Shimano Di2 compatible should you want to future proof or go electric out of the box.
The RS-1 variant tested shares the same tooling as the Ti (Team Issue) version only differing in the carbon fibres used in the layup. The key difference comes in the added stiffness on the Ti version, but frankly, as you’ll see later, I’m not sure any more stiffness is needed.
One thing which resonates from the team at Swift Carbon is that they are all about the detail. This carries right through from manufacturing to end product specification. One example of this is something called Finite Element Modelling (FEM) where they use digital models to understand how the choice and direction of carbon fibres impacts the frames response to loads. This lets them optimise various points on the frame to ensure that they exhibit the desired properties.
Look behind the brand and much of this obsession with detail stems from Mark Blewett - a South African ex-pro cyclist with a background in industrial design. Based just thirty minutes from the production facility in China, Mark has been integrally involved in the development of the bikes and is able to ensure his high-quality standards are continually achieved. Mark also happened to ride from Cairo to Cape Town on an Ultravox late last year.

The build / finishing kit
The Ultravox RS-1 is specced by the team in Cape Town and each component has been incredibly well considered. As a result, there is nothing I would want to or need to change out of the box. Of course, you could add a race day carbon wheelset into the mix and with this in mind Swift do offer an “Ultegra Race” build with your choice of Zipp Firecrests (202, 303 or 404’s). That is of course if your wallet has a bit more appetite.
The model tested was fitted with full Shimano Ultegra, a Ritchey WCS finishing kit and Mavic Aksium Elite wheels. The Shimano Ultegra groupset already has a reputation that needs no fluffing or further mention aside from the semi-compact (52-36) chainring combo which should provide an ideal range for most riders.
The Ultravox RS-1 is topped off with Ritchey WCS alloy bars, stem, and seat post with a Ritchey Streem V3 WCS saddle. I’ve always been a fan of Ritchey components in both function and form. Much like the Ultegra group, the WCS range offers a great mix of proven reliability, performance, and weight. Here the attention to detail from the Swift team is evident in a choice like Ritchey’s 220-degree stem which is said to create a more secure stem-handlebar interface and still shaves grams.
The Mavic Aksium Elite wheels are wrapped in Mavic Yksion 700x25C tyres in line with the trend towards wider tyre widths. The Aksiums are very much an entry to mid-range wheel and although they do not quite stack up to the rest of the build, they offer incredible stiffness and great ride quality at a reasonable weight of 1735g for the pair.
On the road
The Ultravox’s stiffness and the immediacy of power transfer through the lower frame are evident as soon you get going. So much so that I had my doubts about comfort on longer rides. The Ultravox does have an incredibly firm ride, yet, contrary to my initial expectations, it is smooth and surprisingly forgiving. The leaf-like seat stays combined with the added tyre width help soak up most of the bumps. In testing on a selection of Cape Town’s most dubious road surfaces the ride remained comfortable and stable.
Out of the saddle that feel of stiffness carries through into the meaty headtube. Every ounce of effort driven through the pedals appears to push you forwards with no observable lateral flex under heavy loads. This makes for super fast acceleration and an overwhelming sense of efficiency in each pedal stroke. The sturdy front end does mean you get a touch more feedback from the road and on longer rides you might notice a little more fatigue in the hands and arms. But for the overall ride quality and efficiency it’s a trade-off worth making and easily addressed with padded gloves or bar tape.
The Ultravox felt comfortable from the outset, no doubt in part thanks to the extra attention paid by the Swift team to ensure our test model was set up just right (just as they would for a paying customer). Overall the bike has a very assured and composed feel which carries through to its handling. Often new bikes require a few ice-breaker rides, but the Swift had me confidently lunging into corners on our first outing. The handling is superb, striking a perfect balance between stability and agility.
The Swift Ultravox delivers on its promise as an all round pro-level road racer. The incredibly stiff frame makes for an efficient and agile machine with a geometry that just feels right from the get go. For the more serious racer the wheels are an area with potential for upgrade, although the Mavic Aksiums will serve very nicely as a top notch everyday wheelset. Overall the intense attention to detail in the Swift Ultravox provides a package that is tough to beat on feel, performance and, thanks to their direct-to-consumer model, on price too.
