Behind the product
Sticks and stones shred lightweight bib shorts, and they’re often unavoidable obstacles on trails. Our XC Bib Shorts balance the breathability and stretch of our road bibs with the thigh-girding protection of ripstop panels on the outer legs. The final construction is the result of prototype testing on the legs of our World Cup riders, who swept the 2017 team standings while assuring us that these are the most breathable abrasion-resistant bib shorts they’ve ever worn.

Technology overview

The finer details


The dyneRope tex mapping the outer thighs is 15 times stronger than steel. Calling it “abrasion- or cut-resistant” is an understatement. We also engineered some mechanical stretch into the woven material, and the main body of Type.429 Titanio adds additional race-fit stretch and support in less exposed areas.

We adapted our road racing approach to fit, creating a compressive, aerodynamic silhouette that feels restrictive while on foot but becomes a second skin in the riding position.

Y7 frame carrier bibTech: The bib straps lie wide and flat, reducing restrictions on shoulder motion and eliminating ridges under the jersey.

MTB-specific leg grippers: A durable strip that provides compression and grip to maintain fit while whipping through switchbacks or muscling the bike up rock-riddled climbs.

Off-Road Insert EVO: A patented elastic insert interface, with targeted thickness at the rear for optimal comfort and support in the more upright mountain-bike position.

goldenGate: A stitching pattern that anchors the front and back but lets the insert’s body float, allowing the insert to move with your body rather than against it.

ASSOS Waffle: Three layers of foam with perforations and voids that shed weight, increase breathability, and create a structure that compresses and springs to return.
