Collection: Q36.5 • Gregarius Pro

Q36.5 Gregarius Pro is a fully re-engineered cycling system for 2025—built from 100% proprietary materials and designed to deliver the lightest, least restrictive ride feel imaginable. Whether tackling high-altitude climbs or training in peak summer heat, the Gregarius Pro line offers an unbeatable blend of breathability, aerodynamic performance, and ergonomic support.

At the core of the collection are the Gregarius Pro Bib Shorts, constructed from four high-performance fabrics and finished with minimal stitching for a seamless, second-skin fit. The innovative QLAB Air Chamois features an open-layer structure that adapts to rider position in real time, eliminating friction while enhancing stability and airflow. The entire bib short is engineered as a single integrated system—from the straps to the foam pad—to move with you, not against you.

Complementing the bibs is the Gregarius Pro Cycling Jersey, built for warm-weather performance with a honeycomb mesh back, ultra-light front panels, and ribbed aero sleeves that contour perfectly to the arms. The result is a race-optimized fit that’s both aerodynamic and thermoregulating, keeping you cool during the most intense efforts.

The collection also includes matching Gregarius Pro accessories, made with the same recycled, high-performance Italian fabrics—engineered for riders who demand nothing less than peak performance with every pedal stroke.
