Specialized Ground Control Sport Tire (650B)

It's back! This early 90's stalwart has been updated with new materials, a new tread pattern, and new technology. This version of Specialized's Ground Control Sport Tire is a confident-cornering tread that excels in a variety of conditions. Specialized used finite element analysis to optimize the side knobs for grip, create a fast-rolling center section, and provide great braking control.
