Description
HopUp stability snob
An interesting concept that delivers amazing results! Instead of the usual tubular seal, this H-shaped seal forces the hop rubber into a more natural shape around the bottom bracket. Instead of the hop rubber just gripping the top edge of the bottom bracket, the "H" packing grips a much larger surface area and therefore provides more spin and a finer adjustment.
