The Haro Top Am is also equipped with 44/16 freewheel gearing. This allows the rider to shift gears as fast as needed, which is a must for any serious racer. The SINZ Sticky Grips help the rider feel in control of their hold, even when things get dicey. The reviews of the Haro Pro-Am series have been generally positive, and the Haro Top Am, with the positive reviews it has received, is no exception.
