ASSOS cycling shorts contour to your body without the restriction of bibs. The waist of the shorts is made with no pressure elastic so they fit without chafing your waist. The spandex in the shorts is designed with ASSOS’ Elastic Interface Technology which has placed an elastic short insert into the shorts. The insert expands and contracts with every pedal stroke. Your ASSOS cycling shorts follow your movement, causing less friction and irritation. In this design there is also no bunching of material, no wind drag, no snagging. Stitched into shorts are 6 panels with an Advanced Aerodynamic Pattern Design. Aerodynamics and compression are incorporated into this design. Muscle compression reduces fatigue and allows you to ride longer and feel good. Your performance is enhanced when you wear ASSOS cycling shorts.
