ASSOS Size Guide

Fit

ASSOS apparel is cut to mirror your body on the bike, whether that's in our streamlined regularFit or second-skin racingFit. It's normal to feel bib straps and fabric pull while standing. When you move into the riding position, you'll feel the garment "click" into place — disappearing the moment you start pedaling.

Super Aero

An ultra-close, second-skin fit designed to minimize drag in aggressive riding positions, using highly compressive fabrics for maximum aerodynamic efficiency.

A tight feel is intentional.

Racing

A close, performance-oriented fit designed for high-intensity riding, using compressive fabrics for stability and support.

Compared to Regular, it will feel noticeably tighter by design.

Regular

A balanced technical fit combining comfort and performance, using moderately compressive fabrics for everyday support.

Supportive without the tight sensation of Racing styles.

Comfort

A relaxed, versatile fit with minimal compression, designed for freedom of movement and lasting comfort.

A relaxed feel prioritizing comfort and mobility.

All measurements are body measurements, not garment measurements. For best results, have someone else take your measurements while you stand straight.
