Stans NoTubes Crest MK4 700C Rear Wheel 12x142 Shimano HG Tubeless Ready

The Stan's NoTubes Crest MK4 700C wheelset redefines performance for Gravel and XC enthusiasts who demand a lightweight, durable, and fast-rolling wheel. Crafted from 6069 alloy, the Crest MK4 rim delivers exceptional strength with its reinforced spoke bed and welded seam construction, designed to handle a wide range of tire pressures—from 40mm gravel tires to 2.3-inch mountain bike tires. Its 25mm width and asymmetric design optimize spoke angles, creating a stronger, more resilient wheel that excels in both road and off-road conditions.

Equipped with Stan’s patented Bead Socket Technology, the Crest MK4 rim ensures an airtight tubeless seal that is both reliable and easy to inflate. The wheelset uses proven traditional J-bend spokes, all sharing a single spoke length for simplified maintenance and replacement. This thoughtful design means riders can keep their wheels in top shape with minimal hassle, ensuring long-term ownership and performance.

The heart of the Crest MK4 wheelset lies in its M-pulse hubs, developed in collaboration with Project321 and CNC machined in Oregon. These hubs feature a revolutionary Neodymium magnetic pawl system that guarantees rapid engagement (just 1.66° rotation) with virtually no drag, enhancing acceleration and efficiency. Built with Enduro bearings and a robust 7075 alloy 17mm axle, the hubs are engineered to withstand double the force of previous models, while their shielded design protects against the elements for extended durability. Adjustable bearing preload allows fine-tuning for reduced friction, ensuring a smooth, responsive ride every time.

Available with Shimano Micro Spline, HG, or SRAM XDR freehub options and compatible with both 6-bolt and Centerlock brake systems, the Crest MK4 wheelset offers versatile axle configurations to suit all popular setups. Tubeless ready and supplied with pre-installed rim tape and presta valves, these wheels are ready to roll straight out of the box. The Stan's NoTubes Crest MK4 is the ultimate choice for riders seeking a legendary combination of strength, speed, and ease of maintenance in a modern wheelset.
