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

The Stan's No Tubes Crest MK4 Rear 29 12x148 MicroSpline wheelset represents a refined engineering achievement tailored for serious Gravel and Cross-Country (XC) cyclists. Designed with precision from durable 6069 alloy, this wheelset balances lightweight construction with robust performance, ensuring it meets the rigorous demands of diverse terrain challenges. Its 25mm wide rim, featuring an asymmetric profile and a reinforced spoke bed with a welded seam, optimises spoke tension and structural integrity while supporting a broad range of tire sizes—from 40mm gravel tyres to 2.3-inch mountain bike tyres. This versatility makes it an excellent choice for riders seeking dependable performance across mixed surfaces.

At the core of the Crest MK4 is the innovative M-pulse hub, developed in partnership with Project321, which incorporates a magnetic pawl mechanism using Neodymium magnets. This advanced design ensures rapid engagement with minimal drag, enhancing pedalling efficiency and responsiveness. The hub's construction utilises Enduro bearings and a 7075 alloy 17mm axle, housed within a shielded casing that protects internal components from environmental exposure, thereby extending the wheelset’s operational lifespan. Compatibility with Shimano Micro Spline, HG, and SRAM XDR freehub bodies, alongside options for 6-bolt or Centerlock brake rotors, provides seamless integration into a wide array of bike builds.

Pre-installed rim tape and presta valves make the Crest MK4 tubeless ready, leveraging Stan’s patented Bead Socket Technology to deliver an airtight seal that simplifies tyre inflation and enhances puncture resistance. This wheelset is engineered to provide reliable traction, comfort, and durability, whether navigating rugged mountain trails or fast gravel roads.
