SRAM presents lightweight XC wheel

With the "Rise", Sram pulls a light and stiff cross-country wheelset out of the innovation pot. These are 29-inch wheels with carbon rims for tubular tires. The "Rise" is also matched to the new RS-1 upside-down fork from Rock Shox.

With the "Rise", Sram is launching a 1285 gram cross-coutnry racing wheel that combines low weight, stiffness and therefore the best riding characteristics. As they are often used in cross-country, Sram also relies on tubular tires. The "Carbon Tuned™" tubular rim serves as the carrier. By selectively weaving carbon fibers in high-stress areas and using unidirectional fibers, Sram creates a lightweight, responsive and durable rim. The connection to the hubs is provided by the butted stainless steel spokes.

Sram's new Rise hub should also contribute to the high rigidity of the wheel. The "Torque Tube" axle of the Predictable Steering front hub, which creates the connection to the new Rock-Shox RS1 upside-down fork, plays a central role here. This has a larger diameter in order to fix the fork ends together with the new "Maxle Ultimate". This is intended to achieve high rigidity and therefore precise handling. The rear wheel hubs are XD - for 11-speed cassettes - compatible and, in addition to the "Rise", are also built into the "Roam 50" enduro wheels.

The Rise hub is equipped with the precise "SPEEDBALL™" ceramic bearings. Thanks to their lower friction, such a freewheel has less resistance, which means less energy loss for the rider. In addition, thanks to the "SPEEDBALL ™" bearings, no play needs to be adjusted.

The Rise wheels should be available in May 2014.
