It seems Hope has been producing beautifully crafted CNC'd mountain bike parts for as long as we can remember. For 2016, Hope has unleashed the Pro 4 hub, revamped with all sorts of new tech. The Pro 4 packs the same legendary CNC'd hub shell that we've come to know and love on the previous Pro 2 and Pro 3 models. However, they've increased the flange diameter on the Pro 4, which Hope says will increase wheel stiffness. They also increased the hub shell diameter, which has also allowed them to increase the size of the ratchet mechanism in the freehub, increase the size of the main driver bearing, and increase engagement as well. The Pro 4 now offers 44 point engagement - every 8° rotation - which is plenty for most mountain biking scenarios. The larger diameter driver bearing lends extra stiffness, and a longer life. Despite the increased dimensions, weight has remained about the same as the previous Pro 2/Pro 3 hubs.
