Tip: The positions you use on the flats or downhills are entirely different than how you sit on the bike for a climb. With low speed there is little concern for aerodynamics. Sit up, move your hands to the “tops” of the handlebars or the rubber brake hoods. Move your butt a little back, keep your chin up, and relax your shoulders.
Tip: Being comfortably on the bike is often a matter of wearing cycling specific clothing. Check out our What to Wear Guide for more cycling clothing advice.
