Hope Pro 4 12x142mm 32H Rear HubHope has been producing beautifully crafted CNC'd mountain bike parts for as long as we can remember. Hope's latest iteration of their legendary Pro rear hub has been revamped with all sorts of new tech. The Pro 4 packs the same reliable 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 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.
