Made custom for WRC by Specialized, the WRC RBX bib shorts provide comfort and performance in spades.

When it comes to choosing the perfect pair of bib shorts, comfort is everything. And for anyone whose rides demand premium materials, superior fit, and cutting-edge technologies, the new RBX bib shorts are sure to be your jam.

Specialized designed an open suspender fit and bib construction that's engineered to keep the shorts up and in-place without constricting the upper body. The stretchy elastic suspenders are uber plush and soft against the skin, and accommodate taller torso lengths with ease. A non-stretch, sail cloth center back panel is laser-cut for breathability and anchors the back of the shorts for added stability. Silicone-infused fabric cuffs, meanwhile, provide a gentle, secure hold on the legs in order to ensure the perfect, shift-free fit.

The new Body Geometry Contour chamois also adds unrivaled comfort by minimizing its total footprint and keeping only what's structurally necessary. This minimizes pressure on nerves and soft tissue, while also maintaining the optimal level of support.
Last, but certainly not least, the new RBX includes three SWAT™-inspired rear pockets that are engineered into the back of the bibs to house valuables, like ice cream money and keys. Each pocket has clean, bonded edges that stretch, recover, and accommodate its contents with ease.

• Four-way stretch fabric provides ample comfort and a soft hand.
• Soft mesh bib uppers with binding provide a comfortable hold and keep your gear secure with three SWAT™ pockets.
• Silicone-infused fabric cuff provides a gentle, secure hold on the legs in order to ensure the perfect, shift-free fit.
• Articulated design ensures the perfect fit while in the riding position.
• Reflective elements increase your visibility to motorists in low-light conditions.
• UPF 50+ rating protects your skin from harmful ultraviolet rays.
• Single-density-foam Body Geometry Contour Chamois is pre-molded to match the shape of the body for exceptional comfort.
• Mid-sizing provides a shorter inseam and bib strap length for smaller riders.
• Slim Fit with a 10.5" inseam (size Medium).
