I am noticing that my bike shorts no longer stay in place like before...that is the leg grippers are riding higher up my legs and stuff begins to bunch up in my seat. On rides of 20+ miles it starts to hurt. Anyone know a way to shrink bike shorts?These are good shorts that I loved earluer this summer...always cold water wash and air dry them ...I guess my lower thigh shape has changed??Thes eare mediums and I doubt I could fit this butt into a small Any advice or similiar experience.....
