Perfect Fit

I prefer a slightly forward posture for best bike control in twisties and elsewhere and the BC low rise bolt clamps did the job well by lowering my handlebar to an ideal location. I'm 80 and live in the Smoky Mountain where curves are a reality every time I ride. The BC risers fit perfectly, work well, look great and evoke comments from other riders. I'm delighted!
