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.

For any claim, reply to your order confirmation email or write to info@rule28.com with your order number and clear photos. We’ll handle it the same day.

Crash Replacement

If the worst happens and your kit is damaged beyond repair in a crash, send us clear photos of the damage along with your original order details.

We’ll sort a discounted replacement the same day we receive them. Like-for-like where possible.

This sits alongside the standard one-year manufacturing warranty and doesn’t cover normal wear or misuse.

Just email info@rule28.com — we’ve got your back when the road doesn’t.
