Stans NoTubes Arch MK4 Rear Wheel - 29" | Clincher | Centerlock - 12x148mm Boost - XDR

Whether it's All-Mountain, Cross Country or Enduro, if you want to push your limits on uphill, downhill and any type of trail, this is your wheel.

The Stan's NoTube Arch is light enough for fast XC races and at the same time the result of intensive research as well as test runs on the Enduro World Series circuit, which makes it a great wheel for anyone who wants to improve both the climb and the descent. The rim is made of a lightweight as well as strong 6069 aluminum alloy with a reinforced spoke bed and an inner width of 28 mm, which is ideal for 2.2 to 2.5 inch tires. The proven asymmetrical design of the rim gives additional stability while reducing the weight. This gives it a balance between control as well as weight and makes it the perfect choice for all-round riders.

The innovative M-Pulse hub features a set of robust Enduro bearings in combination with a 17mm axle made of 7075 aluminum. Compared to old hub designs of Stan's, this gives it the ability to withstand twice the load. Another special feature is the adjustable preload, which is to minimize the friction as well as the wear of the bearings. This leads in turn to a smoother running wheel and thus to more speed. In addition, the shielded design of the M-Pulse hub protects the bearings from direct exposure to the elements and thus ensures a long service life.

The wheel is rounded off by the proven Sapim D-Light spokes in J-Bend design. They provide the necessary stiffness and their low weight also contributes to the agile handling of the wheel.

BST Asymetric

The proven and patented Bead Socket Technology guarantees high tightness in tubeless operation. In addition, the asymmetric rim shape with staggered spoke holes provides greater stability of the wheel and also saves weight.

WideRight

This rim profile allows the tire to take its ideal shape and forms the basis for great handling, fast rolling and high responsiveness.

M-Pulse hub

At the heart of the hub is a magnetic clinker system developed in collaboration with the company Project321. The precise freewheel has 6 pawls which are equipped with neodymium magnets and engage all 1.66 °. The technology lets the pawls engage with more force than conventional spring systems and reduces resistance when rolling out. Also the wear of the pawls and the entire freewheel system is thus reduced to a minimum.
