Women's Summit Stratos "12-Hour" Bibs

Regular price$259

This ultra-endurance bib is the ideal choice for those seeking guaranteed comfort over extended pursuits, long-distance rides, and races. Its uppers have been modified to maximize stretch and convenience over the prior model, while the leg bands have been replaced with a custom-designed silicone-printed, raw-edge band for a secure, aesthetically pleasing fit.


The Summit Stratos is the original 12-Hour Bib™. It includes the one-of-a-kind Elastic Interface® Endurance Anatomic Super Air Chamois that has proven to provide lasting comfort for rides that go all day and into the night. Custom designed to our specifications, the Super Air Chamois offers optimal breathability and superior endurance comfort through the combination of different foams and densities, delivering unparalleled support in key pressure zones.

The extremely durable Cerami–K fabric, noted by its unique dotted pattern, provides uninhibited movement, long distance comfort and heat dissipation during maximum exertion. Lightweight mesh and raw-edge uppers give excellent support while also offering an accommodating fit for a variety of torso lengths. Raw-edge leg bands guarantee a slip-free yet non-binding fit. These bibs are the ideal choice for those who want guaranteed comfort.

Women's 12-Hour Cycling Bib Back Uppers

Minimal Uppers

The redesigned uppers are not only extremely supportive, but incredibly comfortable as well, so much so, that we say they will disappear during your ride. To accomplish this, we've used a combination of breathable/lightweight mesh around the waist and raw-edge cut, double-knit fabric for the shoulders and front straps.

Endurance Chamois
Anatomic Gem 2

has a one-of-a-kind perforated underlayer, offering exceptional comfort and breathability over long distances. The new “combination foam insert” provides differentiated density in key pressure zones (ischial and pelvic track) making this pad perfect for long distances rides and at the same time it adheres softly to the female athlete’s body.
