Aimed squarely at the top end of cross country race performance, SRAM have developed Rise XX; a wheel set you’re going to see on a good number of World Cup racer’s bikes. Rise XX naturally tops the company’s Rise range of carbon wheelsets, and will be available in 29″ only, with a rim ready to take tubular tyres.
Further improvements come in the form of the new double time ratchet in the freewhub to create quicker and more reliable engagement and the addition of precision ceramic bearings to minimise friction and improve longevity.
With a refined product developed for podium chasers price was never going to be budget, let’s face it; a wheelset is going to set you back a cool £2500′ish.
Here’s SRAM’s words on it…
New SRAM RISE XX Wheels
To achieve perfect balance. To remove limitations. To take every race to new heights. RISE XX — the XC racing wheel for riders who never compromise. Ultra-light, tubular, 29” CARBON TUNED rims. DOUBLE TIME hubs with SPEEDBALL Ceramic bearings. Every detail designed to deliver the competitive edge that every racer seeks. Also available with SRAM’s revolutionary PREDICTIVE STEERING Technology for unmatched balance, stiffness and stability when matched with the RockShox RS-1 fork. RISE XX. RACE FORWARD. RISE HIGHER.

RISE XX TECHNOLOGY
Ratcheting up the smarts. This straight-aligned, 4-pawl design turns the 26-tooth ratchet ring into 52 points of contact. The result: smooth 6.9-degree engagement without reducing tooth size or offsetting internal geometry—which means serious long-term durability.
The only adjustment they’ll ever need was made back at the factory. Every part of the ball bearing comes from the exact same supplier—which means that each bearing bore can be precision machined to fit the bearing race exactly. With tolerances this tight, the days of adjusting play after every ride are over. Now SPEEDBALL bearings are available with ceramic balls for faster, smoother and longer lasting bearings.
CARBON TUNED™ tubular
Strong like bull, light like carbon. Every CARBON TUNED rim is designed with a distinct style of riding in mind. By selectively layering woven carbon fiber at high-stress points and using unidirectional fiber throughout, SRAM creates rims that yield unprecedented low weight to create responsiveness, while maintaining strength and durability.
XD™ DRIVER BODY
XD™ is a cassette driver body design that allows the use of a 10-tooth small cog and provides an improved interface with the cassette.
SIDE SWAP™ SYMMETRICAL
Switching axles has never been easier. Threadless side caps can be installed and replaced by hand—no tools necessary. SIDE SWAP SYMMETRICAL side caps refuse to take sides. The left side cap is identical to the right one. No need to figure out where each cap is going.
Erase uncertainty with PREDICTIVE STEERING, SRAM’s new XC hub technology engineered for unprecedented stiffness and precision. Predictive Steering grew out of a frustration that every XC rider knows: subtle give-and-take at the fork-hub interface can lead to massive frustrations on the trail. So the SRAM engineers went to work with one word in mind: stiffness. And they designed a system that delivers, but remains one of the lightest around.
Unique fork, axle and compression technologies combine at the core of Predictive Steering. The inverted fork features lower legs that soak the seals in a constant oil bath for optimal bump performance. The fork never shifts thanks to the large-diameter TORQUE TUBE axle that creates an unbreakable bond, locking the lowers in place and maximizing torsional stiffness. The new Maxle Ultimate completes the connection with a tighter, stronger clamping force than you’d expect with a quick release compression system. Compatible with the SRAM PREDICTIVE STEERING hub and the RISE XX, RISE 60 and ROAM 50 wheels, Predictive Steering is the integrated system that lets you become one with your bike.

New SRAM Predictive Steering Hub
ERASE UNCERTAINTY WITH PREDICTIVE STEERING HUB
SRAM’s new XC hub is engineered for unprecedented stiffness and precision. Unique fork, axle and compression technologies combine at the core of Predictive Steering. The RS-1 fork never shifts thanks to the large-diameter TORQUE TUBE axle that creates an unbreakable bond, locking the lowers in place and maximizing torsional stiffness. The new Maxle Ultimate completes the connection with a tighter, stronger clamping force than you’d expect from a quick release compression system.
The SRAM PREDICTIVE STEERING Hub proves that being solid doesn’t mean being sluggish. Super-precise SPEEDBALL™ bearings mean lower resistance, faster revolutions and no more time spent readjusting play.
