The Q36.5 Gregarius Pro Bib Shorts are performance cycling bib shorts designed to provide long-distance comfort, stable support and a lightweight, unrestricted feel on the bike.
Redesigned around Q36.5's proprietary construction system, the Gregarius Pro combines an ergonomic four-fabric pattern with the Q LAB Air Chamois, lumbar support and raw-cut leg hems for road training, endurance rides and demanding days in the saddle.
Q LAB Air Chamois
The Gregarius Pro uses Q36.5's Q LAB Air Chamois, developed to adapt to changes in riding position while maintaining support and comfort.
Its two-layer construction allows the different parts of the pad to move independently, helping maintain consistent contact and protection whether riding upright, climbing or holding a lower road position.
Lightweight and Breathable Construction
The upper layer uses a lightweight single-layer cover designed to promote airflow and rapid drying.
Underneath, the C-shaped foam structure is integrated directly into the pattern of the bib shorts, helping reduce unnecessary material overlap while maintaining stability during long rides.
Ergonomic Four-Fabric Construction
Q36.5 builds the Gregarius Pro around an ergonomic pattern using four different fabrics.
Each section is positioned according to the support, stretch and breathability required in that area, creating a close cycling fit without relying on excessive seams.
Minimal Stitching
The pattern uses as little stitching as possible to reduce potential pressure points and help the bib shorts move naturally with the rider.
This minimalist approach contributes to the light, unrestricted feel that defines the Gregarius Pro.
Lumbar Support System
A proprietary high-density woven panel provides additional support around the lumbar and gluteal area.
The panel helps stabilize the upper section of the bib shorts and maintain a secure fit during sustained road efforts, climbing and long-distance riding.
Support Without Excessive Compression
The Gregarius Pro is designed to provide muscular support while maintaining a less restrictive sensation than more aggressively compressive race-focused bib shorts.
This makes it particularly versatile for everyday performance riding and longer training sessions.
Raw-Cut Leg Hems
The leg openings use a raw-cut construction rather than conventional elastic or silicone gripper bands.
This allows the hems to remain securely positioned while reducing concentrated pressure around the thighs.
Smooth, Low-Pressure Fit
By removing bulky elastic bands, the Gregarius Pro creates a smoother transition between the fabric and skin.
The design helps maintain stability without creating unnecessary pressure points during repetitive pedaling.
