THE GOLD STANDARD
FOR HANDLING
IN FULL CARBON FIBRE.

Even with the technological advancements in materials and manufacturing, tuning the ride quality of a bicycle frame still remains an art. In the ever-dynamic task of creating the perfect ‘feel’, balancing weight, stiffness and handling, the Ultravox RS-1 has a fourth factor added to the mix – value. But we would only allow this on one condition, this factor should have minimal impact on the other three.

Box-section head tube, down tube and BB boost power transfer.

Stiffer headtube area improves sprinting and climbing performance.

New lay-up and production methods results in 8% stiffer and 40g lighter frame set.

More high-modulus carbon filaments provide improved stability and handling.

Full carbon PF30 bottom bracket shell.

Frame
Design

To offer this Ultravox to a wider market, we had to reduce the amount of very expensive high-tensile fibres and still retain the frame’s stiffness. We reckon we cracked the formula, creating a lay-up schedule and specifying a paint that retains the SwiftCarbon ride quality, while shaving off the grams.

The RS-1 inherits trickle-down tech from the Ti – like the one-piece all-carbon bottom bracket shell.
