Fully UCI-legal. Designed to work with ANY smooth armed suit or jersey. Worn across more than half the WorldTour peloton and by multiple men’s and women’s Tour de France overall winners.

Developed at the Silverstone Sports Engineering Hub. Macro-scale subsurface ribbing trips the boundary layer over the arms earlier and more consistently than traditional surface textures, delivering greater drag reduction on any untextured skinsuit sleeve.
The same proven structure is now built directly into the full Neo Collection suits, socks, and overshoes.
Usage

Built for riders looking for the highest performance level possible. Especially relevant for high-speed racing.

Technology

Aero

The Neo suit uses a ribbed under-layer under a smooth upper surface to deliberately “trip” airflow into turbulence around the arms which moves the air-separation point downstream, shrinking the low-pressure wake and reducing overall drag. By combining optimized rib-spacing (macro-structure) under a low skin friction outer layer, the suit achieves substantial drag reduction - translating into substantial power savings for the same speed.

Second Skin

Custom made, ultra-low skin friction fabric, made from very fine, high density fibres hides the body from the wind.

Warranty

All pieces carry a one-year manufacturing warranty from date of purchase. This covers defects in materials, workmanship, and construction faults. Thsi does not extend to normal wear and tear, or improper care. This warranty only applies only to purchases made directly through our site.

Crash Replacement
