Castelli Free Aero Race 4 Bib Shorts Kit Version - SS21
The Free Aero Race 4 Bibshort is Castelli's top race short, which also means that it’s insanely comfortable. The original Free Aero Race Bibshort was first introduced over a decade ago and has logged literally millions of kilometers under the backsides of Castelli's pro riders and has been the best-selling short in the Castelli retail collection.
Over this time the short has undergone numerous updates and improvements in the never-ending quest to create the best short possible. While the basic concept of a minimalist workhorse pro-level comfortable race short remains, every single fabric, component, stitch and construction method has been updated and improved over time.
This fourth generation of the short features the updated Progetto X² Air Seamless seat pad. This pad separates a soft, stretchy skin care layer that moves with your body from a generously padded cushioning layer that replicates the form of your saddle. Eight-hour rides are no problem. Of course the fabrics are premium, made to our specifications by Italy’s best fabric suppliers. The Forza fabric on the inner leg features 38% Lycra® content for perfect fit, while the Vortex fabric on the side panels is dimpled for aerodynamics. And it’s held in place by the latest iteration of our seamless flat Giro leg gripper.
  • Vortex dimpled fabric on legs for aero performance
  • Forza fabric on inner legs with 38% Lycra® content for perfect fit
  • Stripe mesh engineered minimalist bib construction keeps you cool
  • Giro4 leg gripper elastic for better grip distributed over larger area
  • Doppio V construction in front for increased support and comfort
  • Flat-lock stitchingProgetto X² Air Seamless seat pad

Mr REES As anticipated these Castelli shorts are very very comfortable. Although expensive I feel they are well made with the crotch padding highly supportive and durable. One can cycle for a long time wearing these shorts. Found from experience, you get what you pay for and these shorts are well worth it.
J Scott Tried them on , love the fit. Can hardly wait for summer, since I live on the prairies in Canada.
Ben Excellent product very comfortable, just what i expected from a quality brand highly recommend
Chelsea Very generous padding, makes my other cycling shorts not feel as comfortable in comparison. I would definitely buy them again.
Mr Mandeville These bib shorts feels and fit great. Definitely would recommend!
Mr BLITS Great bib, perfect sizing and compression, I love its padding, great support and comfort ( not spongy)
Jules Excellent fit and finish. The Progetto seat pad and Giro4 leg grippers stay very comfortable. My only grouse is the thin stripe mesh bib straps are very light and have a tendency to bunch up. I am 173cm, 75.5kg. A L fits comfortably.
Mr Armstrong I have to confess that Castelli is my go to brand for most cycling kit. These shorts are yet another example of an excellent product from the Italians. Quality and comfort are both A1 and exactly what I have come to expect. All combined with the great service and price from Merlin Cycles. You can't go wrong.
Mr McG Great product, if you are new to cycling, or otherwise, it's worth getting the right kit.
