Stan's NoTubes Wheels with White Industries Hubs

What Stan's NoTubes rims and White Industries 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.
• Titanium freehub bodies. The T11, CLD, XMR and MI5 rear hubs use a 6/4 titanium freehub body. On the CLD, XMR and MI5, two of the four Enduro cartridge bearings sit in the freehub and two in the 6061-T6 aluminum shell, which White Industries says gives smooth rolling and long life.
• Three pawls and a threaded drive ring. Three heat-treated steel pawls on stainless steel leaf springs catch a 48-tooth steel drive ring threaded into the hub shell, for 48 points of engagement, or 7.5 degrees. White Industries says the whole hub is easy to service and rebuild.
• A design with a long record. These hubs descend from the Ti Cassette rear hub of 1992, which White Industries says was the lightest on the market at the time. It says that cassette hub design has stayed basically unchanged for 30 years.
