Hope was on hand with these lovely boosted versions of their new Pro 4 hubs. Pressed in bearings for convenience on both of these lovelies, which have been machined out of solid aluminum billet. The front hub is designed with the new 110 hub spacing, and rather than just making a wider axle, Hope has moved the flanges out 5mm to increase stiffness. The front hub is available in 24, 28, and 32 hole configurations; 188 grams for the 32 hole version. The rear features a 4 pawl engagement with 44 engagement points (8.2 degrees for you math nerds out there), comes with either and alloy or steel freehub body, is available in 28, 32, and 36 hole configurations (311 grams for the 36 hole version with the alloy freehub), and like the front hub, the flanges have been moved outboard-this time by 3mm-for stiffer wheel builds. Both hubs come in Black, Silver, Red, Blue, Purple and Orange flavors. 6 bolts rotors only.
