ASSOS uses three trademarked fits:

  • racingFit — second-skin, aerodynamic silhouette inspired by WorldTour research. Compressive thermoregulating textiles. On Equipe RS, Equipe RSR, Equipe R (men) and Dyora R, Dyora RSV (women). If you race, this is the one.
  • regularFit — body-contoured, muscle-wrapping textiles built for all-day endurance. On Mille GT, GTS, GTO, GTC (men) and Uma GT, GTV (women). For most riders new to ASSOS, this is where to start.
  • mobility-enhancing fit — less aggressive than racingFit, prioritising multi-hour comfort and off-bike movement. On Tactica gravel and Trail Tactica MTB.

ASSOS's own line on fit: "It's normal for the apparel to be a bit constricting when standing fully upright, but when you move into the riding position you'll feel the garment click into place and seemingly disappear."

ASSOS runs slim. Most riders take their normal road-bib size in Mille GT / Uma GT (regularFit). For racingFit pieces (Equipe RS, Bolide, Dyora RSV), some riders size up if they're between sizes, especially in jerseys. Race kit is supposed to feel tight off the bike.

The reserve form above asks for height, weight, and chest/waist, plus your usual size in ASSOS or any other premium brand. We'll pull the closest match plus one size up and one down so you can compare on the rack.

ASSOS frames sustainability as durability: build it once, build it right, repair it forever. Every piece carries a 2-year manufacturing warranty, and ASSOS offers a separate owner-funded affordable repair service for damaged kit out of warranty. Care: cool wash inside out, no fabric softener, line dry. Detailed wash labels on every garment.

About ASSOS

ASSOS was founded in 1976 by Toni Maier-Moussa in Zurich. He brought a bicycle frame with teardrop tubes and a bullhorn bar into a wind tunnel and the prototype became what the brand describes as the first aerodynamic carbon fiber frame. The wind tunnel surfaced something unexpected. Wool jerseys produced significant drag. Even bare skin was not the lowest-drag surface. Together with Hans Hess, a Swiss downhill ski racing suit maker, Toni went on to make a Lycra cycling skinsuit.

In the summer of 1976, ASSOS presented the first pair of shorts made from DuPont Lycra. By the late 1970s, the Ti-Raleigh team was racing in them. Within a few seasons, wool shorts had disappeared from the pro peloton. ASSOS is credited with inventing the modern cycling bib short and the anatomical cycling skinsuit.

Fifty years later, the engineering-first DNA still runs the brand. Headquartered in Ticino, southern Switzerland. R&D and design in-house. Production European-only. Trademarked technologies in every garment: goldenGate, rollBar, kraterCooler, INject grippers, Shock-Absorb Damping inserts, the S11 generation. Three trademarked fit systems for three rider needs: racingFit, regularFit, mobility-enhancing fit. The brand has contributed to more than 350 gold medals at World Championships and Olympic Games.

ASSOS calls its output "equipment, not clothing." Built to last a lifetime. Sundays carries the full lineup. Drop by for a fit consultation, try the kit on, ride out of Santa Monica in it.

Destroy. Reset. Improve.
