Cross country control.

The Niner XC Carbon Predictive Steering Wheelset ticks all the boxes for cross-country racers looking for lightweight, bombproof hoops. Boasting industry-leading tubeless design and SRAM's SR-1 hub up front, this wheelset pairs perfectly with your RochShox RS-1 fork to deliver race-ready stiffness, lightning fast responsiveness, and impeccable handling to navigate terrain at speed.

Billed as a fast rolling cross-country wheelset, the Niner XC rim is fashioned from carbon fiber and features a wide 24mm internal width and 30mm outer width to address typical 29er rim complaints by providing a light, stiff platform. Niner borrows Stan's NoTubes' tubeless rim design, dubbed Stan's Bead Socket Technology (BST). BST features low-profile sidewalls that provide a better seat for the tire bead and allow for a pile of benefits compared to standard rims with higher sidewalls. When run as tubeless, BST provides an exceptional seal while allowing the tire to hold a greater volume of air than rims that place the bead 2-4mm below the edge. This interface allows the tire to maintain its full shape for a wider, more stable rolling platform compared to the same tire mounted on a standard rim.

Pairing BST with the ability to run up to 30% lower air pressure than on a standard clincher wheel results in more stability, better handling, solid cornering, and better overall control. These rims are also compatible with standard tubes, and the lower sidewall drastically reduces pinch flat risk by reducing the amount of material present for the tube to pinch against. This means less time sitting in the dust wrestling with a flat at the side of the trail and more time shredding your favorite loops.

Niner utilizes an offset spoke hole drilling pattern in the XC Carbon rim that allows for even spoke tensions across the wheel, which improves lateral stiffness and overall durability compared to wheels with standard spoke holes. This means not only does this wheelset feel faster and more responsive off the line and out of corners, it's also built to withstand whatever you or the trail throw at it.

The front wheel incorporates SRAM's Predictive Steering technology, with a SRAM SR-1 hub specifically designed to match with a RockShox RS-1 fork. While it doesn't actually predict your steering input, this system is so stiff and reliable that it may as well. To adequately unify the new RS-1 fork's two lower stanchions, the 15x110mm Boost Maxle Ultimate thru-axle joins forces with the Torque Tube within the RS-1 hub to create a virtually un-twistable fork/hub interface.

Niner's XC Carbon Predictive Steering Wheelset is available with either a 12x142mm rear axle or a 12x148mm Boost rear axle and is compatible with 6-bolt brake rotors. It comes complete with tubeless rim tape and valve for easy tubeless setup. Please note that the SRAM Predictive Steering RS-1 front hub is compatible only with the RockShox RS-1 fork.
