Simple doesn&';t not necessarily mean you&';re giving up any perks. Especially not with the Rapha Core Shorts - a seemingly simple pair of strapless shorts that provides premium comfort and performance no matter what kind of riding you have on the calendar. Your go-to pair of cycling shorts for summertime riding, indoor training, and commuting. Made using the same collection-specific materials and technology as the best-selling Core Bib Shorts, but without the shoulder straps to help you beat the heat.
