Stans Crest MK4 Rear 29" Wheel 12x148 MicroSpline Tubeless-Ready Gravel XC

The Stan's No Tubes Crest MK4 Rear 29 12x148 MicroSpline wheelset is designed to elevate your Gravel and XC riding experience with its perfect balance of lightweight construction and durable performance. Crafted from 6069 alloy, the Crest MK4 rim features a robust reinforced spoke bed and a welded seam, ensuring it withstands the demands of both 40mm gravel tires and 2.3-inch mountain bike tires. Its 25mm width and asymmetric design not only optimize spoke angles for enhanced strength but also guarantee an airtight tubeless seal through Stan's patented Bead Socket Technology, making inflation easier and more reliable than ever.

Built by riders for riders, this wheelset embraces simplicity and longevity with traditional J-bend spokes, all sharing a single, common spoke length across front and rear wheels, simplifying maintenance and repairs. At the heart of the Crest MK4 is the innovative M-pulse hub, developed in collaboration with Project321. These hubs feature a magnetic pawl mechanism made from Neodymium magnets, delivering swift engagement with minimal drag. The advanced design reduces friction when disengaged, ensuring efficient rolling resistance and remarkable durability thanks to Enduro bearings and a 7075 alloy 17mm axle. The shielded hub design further protects internal components from the elements, extending the lifespan of your wheels.

With compatibility across Shimano Micro Spline, HG, or SRAM XDR freehub bodies and options for 6-bolt or Centerlock brake styles, the Crest MK4 Rear wheel fits seamlessly into a variety of setups. Pre-installed rim tape and presta valves mean it’s tubeless-ready right out of the box, allowing you to benefit from the improved traction, comfort, and puncture resistance tubeless setups provide. Whether you’re tackling rugged mountain trails or fast gravel roads, the Crest MK4 Rear 29 12x148 MicroSpline wheelset offers exceptional strength, speed, and reliability to keep you rolling confidently.
