Superleggera Bib Short

Castelli has long been chasing the perfect ultralight short for hot weather rides, and the Superleggera is their lightest yet at only 141g. Where most bibs use a knit fabric, Castelli developed an ultralight gradient woven textile, which is most robust near the insert to keep it in place and lightest near the hem for maximum breathability. Castelli designed the Superleggera to be every bit as comfortable as their other race bibs with the same mesh bib construction as the Free Aero Race 4 Bibs. A Progetto X2 Air insert reduces friction in the saddle with its seamless upper and helps keep you cool with the perforated cushion layer.

These do match the description from Castelli. The bibs are thin and light and are great for rides on really hot days. But being so light and thin, they do not seem like they would be supportive on longer rides. For my 35 to 45 mile rides they were fine, but I don’t know if I would use these on a century. Out of the box, the material felt rather stiff with an almost crunchy feel. The interior area around legs had a rough texture which was a concern. But once on bike they were fine. The length is bit longer than usual. I’m 5’ 11” and on me they end pretty close to the top of the knees. Consequently, the leg openings looks like they should be tighter. I’ve only worn them a few times and the leg opening are developing an ever so slight ruffle around the edge. But somehow they don’t manage to ride up when I’m pedaling. The straps are flat and are much easier to deal with than the Castelli Free Aero Race 4’s, which are like ropes until you straighten them out. Sizing was typical for Castelli in that they run slightly small. The Progetto X2 Air Is one of the best out there. I took one star off because the leg length should shorter, or given the length, the opening should be tighter. If they stretch out over time, the leg grippers will not be able to hold them in place.

Very light weight -- almost too light. Chamois is top of the line. Fits a bit on the small side. Straps are very light weight and, as such, tend to twist and roll over. But if you take the time to make sure they start out flat and untwisted, they stay that way. They're still too new to comment on how they wear after lots of washes and rides, but I suspect they won't wear as well as their heavier cousin. the legs grip well.
