Evolving from the CX237, Lake has improved upon performance and durability, with its high-cadence riding favorite, the Lake CX238 Road Shoe. Shaped for a better, more comfortable fit, the Competition last increases toe pitch and heel lift, allowing the foot to expand under high pedaling pressure. Supporting the shoe is Lake's Race carbon fiber sole, offering impressive stiffness and power transfer while remaining low in weight. To protect the shoe from premature wear, the full-grain leather upper boasts a panel at the heel and a rubber bumper at the toe, plus mesh panels for proper ventilation. Designed for high-pressure riding, the Lake CX238's wider forefoot provides the relief you need to focus on the road ahead.

A versatile mid-weight cycling jersey made for comfort on any ride. The original Core Jersey set a new standard for the everyday cyclist, now its successor raises the bar again. The updated Core Jersey is made of a new, stretchier fabric for a fit that is close without being restrictive. The fabric is soft and breathable for comfort when next to the skin or on top of a base layer. Its marl finish combines with contrast logos on the rear and the chest and, for the first time, Rapha's signature armband to create a simple, refined look. Our designers have worked extensively on the shoulder seams which have been reshaped to prevent the bunching of fabric under the arms. Raglan sleeves and stretchy side panels provide stability in on-bike positions while a low-profile, laser-cut silicone gripper on the rear keeps the jersey in place. Ribbed material is used at the collar, cuffs, and on the armband for a subtle contrast. Three rear pockets carry ride essentials and have been updated with an elasticated hem for added security. A staple of your cycling wardrobe, the Core Jersey includes everything you need and nothing you don't. - Side panels and raglan sleeves for a perfect fit - Soft and highly breathable matt fabric to keep you comfortable in all conditions - Contrast trims throughout - Ribbed tipping on collar and cuffs - Deep-cut, silicone rear gripper to hold the jersey in place - Three rear cargo pockets with secure storage capacity for all rides - Additional zip-pocket to keep valuables secure - Subtle tonal branding - 100% polyester
