RVE - WarpSpeed® Aero Compression Calf Sleeves

The aerodynamic advantage for triathletes and cyclists

In endurance sports, performance isn't just about power, but about efficiency.

For triathletes and cyclists reaching speeds above 35 km/h, air resistance becomes the biggest barrier to performance. And while most athletes focus on position, bikes, and helmets, there's one factor often overlooked: your clothing.

Why aerodynamics are more important than you think

At race pace, up to 90% of resistance comes from air resistance.

Every small improvement in how air flows around your body can lead to:

• Higher speeds
• Less energy consumption
• Better race results

For triathletes, this is even more crucial. The bike leg is not just about speed, but also about saving energy for the run.

The technology behind WarpSpeed®

WarpSpeed® is an aerodynamic textile system, developed by Liebaert Textiles and validated through wind tunnel testing.

Its core consists of a precisely engineered warp-knit fabric with a specific surface structure that controls airflow.

How it works:

When air flows over a smooth surface (like skin), it detaches early, creating turbulence and drag.

WarpSpeed® fabrics introduce a controlled tri-ladder structure that:

• Activates the boundary layer
• Allows airflow to stay attached longer
• Reduces turbulence behind the leg

This principle is similar to the dimples on a golf ball, which reduce air resistance.

The result? Less drag. More speed.

Aerodynamics + compression

We have chosen to integrate WarpSpeed® into our compression products because performance is not one-dimensional.

Traditional compression focuses on muscle support and circulation. But at race speeds, aerodynamics play an equally significant role.

By combining aerodynamic textile engineering with targeted compression, we bring two performance elements together in one system.

The result: a product that supports your muscles and reduces air resistance.

No more features. But a better integration of technology.

The result? More speed. Less effort.

Tested in the wind tunnel

WarpSpeed® was tested under professional wind tunnel conditions at the Bike Valley Aero Performance Lab (Belgium). Both at the material level and in finished products (sleeves).

Key findings:

• Measurable reductions in aerodynamic drag (CdA)
• Performance improvements at race speeds
• Optimal functioning between 36 and 45 km/h

In cycling-specific tests, this resulted in:

• Up to 5–10 watts saving at 36–45 km/h*

Real gains where it counts

In triathlon and competitive cycling, races are often decided by seconds.

Small aerodynamic improvements can therefore make all the difference:

• Starting the run fresher
• Maintaining position in a lead group
• Gaining time without extra effort

WarpSpeed® focuses on precisely that: maximum efficiency when it truly matters.

In a sport where athletes invest in carbon wheels, aero helmets, and optimized positions, it makes sense to exploit every possible advantage.

WarpSpeed® is based on one simple idea:

If you have less drag, you go faster. Without having to push harder.
