The perfect bib.

I have been riding the Aero Bibs for years, it has taken me on 100+ rides in the Colorado Mountains and all over Europe. It is so flattering on your body and the leg grippers look great and hold the leg panel in place without unflattering bunching/binding. Submitted on  15 October 2019  by  Kristin Weber

Free Aero 4 W Bibshort

I love the grippers on the legs! They won't squish out your thighs :) They feel great. The straps are super comfy too. Much improved design of the original aero bib! You will love the new fabric. Submitted on  13 June 2019  by  @annefrogie


Size Ordered: M Body Type: Athletic; Tall and Slim Height: 5'10.5" USA Pant Size: 2-6 USA Top Size: S Type of Rider: Road Racer I had been wearing the Castelli X2 pad for several years when this new updated version of the X2 came out. This pad is AMAZING. It is the only chamois I will wear on long rides and it is the only chamois I will race in. As for the bibshort itself - I love everything about the new updates except for one tiny detail: while I 100% prefer the new silicon grippers over the mesh on the previous aero race bibshort, the silicon grippers are a bit tight on my legs. Some of my favorite new features from these bibshorts (other than the new chamois of course!!!) are the new back/strap material, and the longer leg length.

Really great bibs, they are comfortable, well padded in all the right places and cool. One note - when I first tried them on the elastic around the lower thigh was loose. After a few minutes they "shrunk" to fit my legs perfectly. Submitted on  28 May 2019  by  Laura

Barely there!

This is one of the most comfortable bibs I have ever owned. As a female with bigger quads, the leg grippers and leg fabric flexes and moves on even the hardest climbing workouts and doesn't constrain at all. Top notch bib guys! Submitted on  25 May 2019  by  Lauren
