"If it aint broke, don't fix it," is a line that was tossed around at Castelli when considering the newest version of the Aero Race bibs. Fortunately for us, Castelli wasn't satisfied enough with the positive feedback from the pros who were using and testing their products. To tweak the best selling Castelli design of 2018, the 2019 version includes a new leg gripper that includes vertical strips of silicone to keep the garment in place without sacrificing stretch. Along with using the same fabric that Team Sky will use this year, the seams have been improved for comfort making the garment flatter and ultimately result in a more durable bib. The Progetto X2 Air seamless chamois is also claimed to be the softest surface fabric you've ever felt in a seat pad, and with its new skin care layer, our hides couldn't be happier.

Note: Castelli apparel is designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.

  • Extremely light and breathable
