New Pro Aero Jersey Testing, Our fastest jersey yet




ENGINEERED FOR SPEED

We took our new Pro Aero Jersey to the Silverstone wind tunnel. The new jersey has been redeveloped with a double layered tripping fabric system on the sleeves, designed to reduce drag for the rider. 

The new system utilises a raised wind channel fabric as the base and a slippery sublimated fabric over this base. This double layered system does not affect heat management as it is only used on the sleeves; the rest of the jersey is single layer and fast wicking. 

What the data showed us particularly in the crosswind conditions that define real road racing  changed how we think about fit.

The new Pro Aero Jersey is the result of extensive aerodynamic development. Tested against the Bora–Hansgrohe WorldTour Team Jersey - a benchmark at elite race pace, it delivers measurable power savings that translate directly into race performance scenarios.

SHOP THE COLLECTION

Test Methodology

To develop the Pro Aero Jersey, we commissioned independent aerodynamic testing at the Silverstone Sports Engineering Hub, one of the UK's leading motorsport and cycling wind tunnel facilities. Every variable was controlled so the data speaks purely to the garment.Testing was conducted at an male Elite and Category 1 race pace of 45 km/h the speed at which jersey aerodynamics have a material impact on rider effort.

Yaw Angles

0° DIRECT HEADWIND

The controlled baseline. Clean airflow striking the rider head-on. This is the lab standard, and an essential point of comparison with published industry benchmarks.

5°  REALISTIC CROSSWIND

The condition that defines actual racing. Wind rarely arrives perfectly head-on. A 5° yaw simulates a typical crosswind scenario and is where real-world performance separates from a direct headwind tunnel claim.

Reference Garment

The benchmark jersey we used as the reference is the BORA hansgrohe Team Race Jersey, our previously fastest short sleeve jersey, tested, developed and proven at WorldTour level, including a Grand Tour victory at the 2022 Giro d’Italia with Jai Hindley.

Test Methodology

Aerodynamic data is only meaningful when we know the body it was tested on. All results were recorded on the same rider throughout the session to ensure full consistency across garment comparisons. These are the rider dimensions:

HEIGHT: 177cm

WEIGHT: 72kg

CHEST: 93cm

WAIST: 69cm

HIPS: 90cm

Key Findings

These principles drove the performance improvements we saw in the Pro Aero Jersey.

Crosswind Conditions Amplify Every Gain

At 0° yaw, the Pro Aero beat the BORA hansgrohe jersey by 7.2 Watts. At 5° yaw the kind of angle you encounter in almost every road race that gap grew to 10.9 Watts. Garments optimised only for straight-line headwind testing are limited when performing on the road.

Seam Architecture Shapes Airflow

The placement and direction of seams across the torso and arms function as aerodynamic guides. The revised seam architecture in the Pro Aero Jersey is designed to direct air cleanly over the shoulders and down the arms, preventing the separation zones that cost watts at racing speed.

Wind Tunnel Results

All figures are measured aerodynamic drag area (CdA) and calculated power savings at 45 km/h. Reference: BORA hansgrohe Short Sleeve team jersey.

* All testing conducted at Silverstone Sports Engineering Hub. Power savings calculated at constant 45 km/h. CdA = coefficient of drag × frontal area.

Headline Results

Pro Aero Jersey:

7W : saving at 0° yaw (direct headwind) vs. BORA Hansgrohe team jersey at 45 km/h

11W : saving at 5° yaw (realistic crosswind) vs. BORA Hansgrohe team jersey at 45 km/h

Expert Validation

“I have independently verified the wind tunnel testing methodology, data collection, and results analysis for the Pro Aero Jersey. The testing was conducted under controlled conditions at Silverstone Sports Engineering Hub, and the measured aerodynamic improvements as stated in this content page are accurate and reproducible."
