Bib shorts designed for longer rides tend to follow a predictable formula: add more padding, use heavier fabrics, extend the leg length. Assos takes a different approach with the Mille GTS Bib Shorts S11 Long, treating the extended length as an opportunity to rethink how the entire garment interacts with your body over multi-hour efforts. The "Long" designation adds approximately 4 centimeters to the leg compared to the standard Mille GTS, which puts the gripper band below the typical flex point of the quad and changes how the fabric tracks during pedaling.
The S11 chamois represents the current generation of Assos padding technology, built around what they call their goldenGate construction. Rather than a single foam density throughout, the insert uses dual-density foam with strategic thickness variations that respond to different pressure points during the pedal stroke. The nose section stays thinner for reduced friction, while the sit bone zones get the bulk of the cushioning depth. It's the kind of design philosophy that only reveals itself after the third or fourth hour in the saddle, when simpler pad constructions start to compress and lose their shape.
The fabric itself is their Type.439 material, which Assos positions as their workhorse textile for temperate conditions. It's a medium-weight knit that provides mild compression without the squeeze of their race-cut offerings, and the weave maintains breathability across a broad temperature range. You won't overheat on moderate days, but there's enough substance here to handle early morning starts when the air still has some bite.... Read More
Assos uses their regularBib construction for the upper, which features a single-piece back panel and twin front straps. This is their comfort-oriented bib architecture rather than the performance-cut ergoBox design found in their race line. The straps sit flat against your shoulders without the pronounced cutouts or floating panels—straightforward and effective. The waist uses a stability doubleBack panel that helps anchor the shorts without relying entirely on leg gripper tension.
The extended leg length serves a practical purpose beyond aesthetics. Positioning the silicone gripper band lower on the thigh moves it away from the area that expands and contracts most during pedaling, which can reduce the gradual upward migration that plagues some shorts over long efforts. The leg panels themselves use a rawCut finish rather than a bound hem, eliminating one potential source of pressure points where the fabric meets skin.
