Free Aero Race 4 Team Bib Short
The Free Aero Race 4 Team 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. As far as the "Team" moniker goes, the only difference we can tell over the standard version is the inclusion of white Castelli lettering at the bottom of the legs.
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.

- Q & A
POWER = COMFORT + EFFICIENCY
- Fit: Runs small
The three things I look for in bib shorts are:
1. No chafing.
3. A snug fit.
The Free Aero Race 4 Team Bib Shorts checks all of these boxes and more. Upon receiving these bad boys the first thing I noticed was how soft the material was for the chamois. The bib short also has built in silicone stripes near the quad that help keep the short from riding up your leg. In other words, you can perfect that razor sharp roadie tan line all summer long. Lastly, the feature that also stands out is the dimpled fabric (just like a Zipp wheel) that provides an aerodynamic advantage that has been thoroughly tested in secret wind tunnels across the country.
Now enough about the features, how do these things ride? Well, I have raced my bike across the country for the last decade in numerous companies products and the Castelli Free Aero Race 4 is in the top of the top. I mean it. But do you really need to be dive bombing corners on bell lap to require the most comfortable bib short? The answer is no. From Cat 1 racer to weekend warrior, do yourself a favor and upgrade to these bib shorts. I gurantee you will never look back (except when you are dropping your friends).

- Familiarity: I've used it several times
- Fit: Runs small
For a few years, one of, maybe the, favorite bibs. Checks all my bib boxes - excellent chamois, great compression and compression has held up, comfortable over long periods, comfortable strap. As usual they run small, Castelli/euro fit, the same as my previous free aero's. Definite thumbs up recommendation.
