Introducing 3 New GT Series Wheelsets
When we launched the Strade GT earlier this year, we introduced something new to the way we think about wheel performance.
For years, the cycling industry has focused on two metrics: weight and aerodynamics. Both remain fundamental to fast wheels, but we believed there was another opportunity to make riders faster, not by reducing drag alone, but by reducing the physical cost of riding at speed.
That thinking led to VibraCORETM, our vibration-damping technology developed to reduce the road buzz and high-frequency vibration that contribute to rider fatigue. The goal was simple: help riders stay fresher for longer.
Today, we're taking the next step.
The Chrono GT, all-new 3S GT and Disc GT mark the next phase of the Parcours GT Series, extending the platform across road racing, time trial and triathlon. Together, they demonstrate that VibraCORE isn't simply a feature of one wheelset, it's become a core part of the engineering philosophy behind the GT range.
The Fastest Rider Isn't Always the One with the Lowest Drag
Aerodynamics matter. Weight matters.
But the fastest rider at the finish isn't always the rider who generated the least drag. Sometimes it's the rider who conserves the most energy along the way.
Whether you're racing in the peloton, riding a national time trial or tackling an Ironman, you're constantly managing more than just watts. Crosswinds, handling, road vibration and comfort all influence how well you can sustain your effort over the course of an event.
The GT Series has been developed around this broader view of performance.
Every wheel is designed around modern 30 mm tyres and shares the same engineering DNA: aerodynamic optimisation, hooked tubeless-ready rims, ultra-light construction, carbon spoke technology where appropriate, and VibraCORE integrated into the rim structure to reduce vibration before it reaches the rider.
The result is greater confidence, improved stability and less fatigue over long rides and races.
Three Wheels. One Philosophy.
Each wheel within the GT Series has a different purpose, but they're united by the same objective.
Chrono GT (62/65mm)
The Chrono GT is our next-generation UCI-compliant aero wheelset, engineered around the latest rim depth regulations.
Using our proven front/rear differential design philosophy, it delivers an 11% reduction in crosswind sideforce while weighing almost 350g less than the existing Chrono wheelset. Despite its shallower depth, it retains virtually all of the aerodynamic performance of its predecessor, giving riders a UCI race-legal wheelset that's lighter, more stable and more confidence-inspiring.
3S GT
The all-new 3S GT is our first-ever tri-spoke wheel and a complete reimagining of what a modern tri-spoke can be.
Designed around a 30 mm tyre, it delivers a total aerodynamic benefit of 2.9 watts over the existing Chrono Max front wheel, combining lower translational drag with significantly reduced rotational drag.
Just as importantly, VibraCORE helps address one of the compromises that has always defined tri-spokes: ride harshness. By reducing vibration transmitted through the wheel, the 3S GT delivers not only greater aerodynamic efficiency, but also improved comfort and composure over long race efforts.
Disc GT
The Disc GT has been developed for riders chasing the lowest possible CdA, but without ignoring what happens after the first few kilometres.
Our testing has shown it records the largest vibration reduction ever measured on a Parcours wheel, reducing transmitted vibration energy by almost 40% in the frequency range most closely associated with rider muscle fatigue.
The result is a wheel that not only reduces aerodynamic drag but also helps riders maintain race pace with less physical cost over long, sustained efforts.
Developed Through Racing
The GT Series hasn't just been developed in the wind tunnel.
Over the past 18 months, we've worked closely with our professional athletes, refining prototypes through racing at Challenge Roth, the T100 Triathlon World Tour and the Ironman 70.3 World Championship.
That development has already translated into results. Ahead of launch, the final production model wheels helped Parcours athlete Lizzie Rayner secure victory at Ironman Pro Series 70.3 Swansea.
The programme has also shaped our approach to the Ironman World Championship in Kona. Extensive wind tunnel and real-world testing identified the fastest wheel configuration for Kona's unique demands, where our athletes will be racing a tri-spoke front and rear setup.
