Pas Normal Studios
The Pas Normal Studios Women's PAS Mechanism Pro Bibs are race-focused cycling bib shorts developed for high-intensity road riding and racing. Built around the Mechanism Pro platform, they combine structurally mapped fabrics with variable 4D-stretch to create targeted support, compression and a close second-skin feel at race pace.
The soft, silk-like stretch-woven main fabric provides a high strength-to-weight ratio while remaining abrasion-resistant and highly breathable. Variable stretch zones are integrated directly into the fabric to support the muscles and create a precise body wrap, while exposed elastane yarn at the leg openings functions as a silicone-free gripper to keep the bibs securely positioned.
A four-layer ultralight foam chamois is positioned specifically for comfort in an aggressive, speed-focused riding position. Quick-drying antimicrobial membranes help manage moisture and reduce friction during longer efforts, while lightweight bib straps and a breathable rear mesh panel maintain stability without unnecessary bulk. An integrated radio pocket provides discreet storage for a race radio or smaller essentials.

Alba Optics
The ABR1 Pocket Bib Shorts are made for the longest days on the bike. Albion developed them with ultra-distance riders, and they've been ridden to wins and record times on the Tour Divide, the Atlas Mountain Race and the Highland Trail 550. If your rides are measured in hours rather than kilometres, start here.
Two mesh leg pockets and a rear side-entry pocket let you carry a phone, gels or a wind jacket without touching your jersey pockets. That's handy on gravel and bikepacking trips, and just as useful on a long road day. Everything stays reachable while you ride.
The Albion x Elastic Interface chamois is built for long hours in the saddle. The 2025 update adds a higher gauge main fabric for more compression and polypropylene-knit straps that move moisture away faster. A hidden Rear Guard panel above the pad makes the shorts last longer.
An on-bike fit that runs true to size, with a reduced number of panels and flatlock seams. Our studio model is 180 cm (chest 91 cm, inner leg 80 cm) and wears size S. Want to compare them with your current bibs? Try them on in one of our stores in Amsterdam, Utrecht or Rotterdam.
