SwiftCarbon Ultravox RS-1

SwiftCarbon UltraVox RS-1.jpg

The Swift Ultravox RS-1 is a full carbon race machine which, on paper, provides unbeatable value. The RS-1 is the second tier in the Ultravox lineup behind the Ti (Team issue) version as ridden by Aussie based Drapac Pro Cycling team. The two models differ only in the carbon fibres used in the layup with the Ti version utilising some of the highest quality (and most expensive) options.

The Ultravox RS-1 is available locally with three build options: Shimano 105, Ultegra and Ultegra Race (including Zipp Firecrest 202/303/404s). Our test model is the middle option kitted out with full Shimano Ultegra, Ritchey WCS alloy finishing kit and Mavic Aksium Elite wheels.
