Here's what others have to say...


Quality Issue

    Experienced the same quality issue mentiioned on one of the reviews. The stitching on the chamois failed after first ride and got worse. Currently in the process of returning the item. Will probably get a Capo replacement.


    Great Bibs -

      Love the look and the chamois, these run small compared to other brands... normally a L in Hincappie, need XL with Castelli


      Great Graphic, runs small

        I ordered a second pair of these because I like the"look" and the pad is Castelli's best; same as in their "skin" bibs. First pair got a hole in them after only a couple of wears/washes. I own many other pairs of Castelli shorts and the small is just a bit loose in most cases, but these are really, really tight. I ordered a M replacement because I thought maybe the hole was because they were too small and stretched too tightly. I hope that's the case and not a quality problem like the other reviewer mentioned. I will definitely look them over carefully when they arrive. I had one other time when Castelli seemed to run small. My guess is that they use different sizing for their European distribution and American distribution, and once in a while they get a European sizing over here. Anyway, definitely recommend at least a size larger than you normally order in Castelli.


        Poor quality.

          Big fan of Castelli; however, the quality appears to be going in the wrong direction. Had to return two pairs of these bibs due to stitching of the chamois not being complete. Finally gave up. I have and use other Castelli bibs in the same style, no issues. I really don't find subjective statements to be much help. So two pairs, both with the same issue should be objective enough.

          what is the inseam length on the Aero Race...

          what is the inseam length on the Aero Race bibs?

          Hey ofe5474839,

          Thanks for your question. The Castelli Free Aero Race Bib Short - Men's have a 9" inseam on the Medium size and it most likely goes to 10" in XL and beyond.
