    Free Aero Race 4 Bib Short

    The Free Aero Race 4 Bib Short from Castelli is built using extensive feedback from the professionals on Team Sky. Its general consensus is the existing Free Bibshort was already pretty well dialed and the only requests were the addition of a loop in the bib to hold a race radio microphone and one rider wanting his chamois shifted back a bit. Team Sky isn't the only one who likes it, in fact, the Free Aero Race Bibshort is the best-selling Castelli short of all time, so it knew that when it was time for an update, it wanted to make it better but not change the shorts too drastically.

    First up is a new leg gripper that still features a lie-flat, raw-cut edge but now has vertical silicone stripes to hold it comfortably in place without restricting stretch. Next is a new fabric that allows for better print quality and Castelli updated the seams to improve the fit and looks. It also re-engineered the bib straps with new fabrics and construction so they help you stay cooler, lie flat, and are more durable. Finally, it also receives the updated Progetto X2 Air seamless seat insert featuring one of the softest surfaces we've ever felt in a chamois.

    • Castelli's most popular bib short, newly updated
    • Vortex dimpled fabric on the legs boost aero performance
    • Forza fabric on the inner legs stretches for a perfect fit
    • Stripe mesh engineered minimalist bib construction keeps you cool

    • Doppio V construction up front increases support and comfort
    • Flat-lock stitching reduces irritation
    • Progetto X2 Air Seamless seat insert cushions against road chatter
    • Item #CST00RY

    Race Ready

    • Familiarity: I've used it several times

    These are actually my first Castelli bibs and they certainly won't be my last! The Progetto X2 Air chamois is quite comfortable for longer days in the saddle. These are a quality product thru and thru. As far as sizing, be sure to size up. I am a size Medium in most other bibs but these Free Aero's in size large feel like a snugger medium to me.

    A New Favorite

    • Size Bought: XL

    Quite impressed by these bibs. Castelli's Free Aero Race shorts have always been a favorite and it looks like these will be at the top of the pile in my closet. Materials are excellent - the Progetto X2 Air chamois has padding in all the right places without excess bulk, the main fabric of the legs is compressive yet lightweight (I expect these will breathe well in summer), and the bib straps seem to lay especially well against my body and are once again quite airy. Usually I prefer seamless elastic bibs (like Giordana uses) but I have no complaints here. Even without the dimpled material on the legs I'm not winning races but it certainly makes me feel fast. Some of Castelli's lesser pieces have had occasional quality issues with the sewing of the seams but construction is excellent here. Lastly the leg grippers are wide and unobtrusive and the inseam length is perfect.

    Once again, the fit is compressive to reduce muscle fatigue in hard efforts or on long days. If you're not familiar with Castelli, in general their apparel runs smaller than American brands and sometimes even a bit smaller than European brands. I wear a large bib in Assos, Giordana, and Pearl Izumi's PRO line, I went up to an XL in this for the strap length as Castelli's straps run short and dig into my shoulders in smaller sizes. The XL's straps are perfect and while I was worried that the body of the bib would be loose and baggy, that's not the case at all due to the compressive material. So if in doubt, size up!

    Great Bibs!

    • Familiarity: I've used it several times
    • Fit: True to size

    These bibs are really nice. Much better than the previous version. They are more durable and they are super comfortable. The material is a bit stronger, so they will last. They are quiet comfortable for those long days in the saddle. The material of the bibs is also super comfortable. Well worth it!
