For our longest, toughest training rides, we kit up in nothing but the Giro Chrono Expert Bib Short to ensure we finish our ride without discomfort. The premium Italian materials used in the Renew Series fabrics are both recycled and bluesign Approved, offering not just comfort and performance but also a low environmental impact. The Chrono Expert Elastic Interface chamois is anatomically formed and features a 13mm thickness for all-day seated comfort, while breathable mesh straps and compression leg grippers keep our bibs securely in place as we push out watt after watt.
