Stan's NoTubes Wheels with Hope Hubs

What Stan's NoTubes rims and Hope hubs each bring

• Bead Socket Technology. Stan's patented rim shape holds the tire by its bead rather than its sidewall, so the sidewall can expand to a rounder profile. Stan's says that means more traction and less rolling resistance than a conventional shape, which drives the bead deeper and restricts tire volume.
• Low sidewalls. Bead Socket rims have lower sidewalls than conventional rims. Stan's says that leaves them less exposed, and makes the rim lighter and stronger.
• Spoke offset set by rim width. On MK4 rims the spoke holes sit 1.5mm off center on the 25mm Crest, 2.5mm on the 28mm Arch and 3mm on the 30mm Flow. Stan's reports 92 percent drive to non-drive tension balance on the Crest MK4, against 58 percent on the symmetric MK3.
• Made under one factory roof. Hope designs, tests and makes virtually all of its products in Barnoldswick, England, from CNC machining through anodizing to hand assembly. Hope says that gives it full control of quality and delivery.
• Offset pawls on the Pro 5. Setting the freehub's six pawls out of step raises engagement from 44 points to 108, and the single speed hub reaches 108 with four. Hope cuts the pawls from high strength steel and says the new pawl and spring design adds load capacity and service life.
• Drag cut at the seal and the ratchet. Hope says the Pro 5's labyrinth seal keeps dirt out with zero drag. On the road, the RS4 rear goes a different way, with a reduced-drag two-pawl ratchet at 44 points, or 8 degrees.
