I tried out my first road bike (a women's specific Madone 6 w/ultegra components) while on vacation this winter, and found that using the hand brakes really hurt my extra-small hands by the end of the ride (muscle pain from using the brakes, not vibrations). Has anyone else had this problem before? Any recommendations for group sets that work well with small hands? Most of my riding has been done on a hybrid with straight bars and top brakes.
