Chafing's probably the most effective way to ruin a good long ride, but Paceline Products' Chamois Butt'r Eurostyle Cream will sooth your skin and lube your legs. It's thicker and creamier than most chamois butters, so it won't rub off or sweat away, has a non-greasy feel, and contains cooling, slightly tingly ingredients such as Brazilian Peppertree, menthol, and witch hazel. It even tightens pores to reduce friction that can bring on saddle sores.
