Feel your bike come alive on the open road with the new Alpinist CL II, featuring the lightest, best-handling clincher rims we have ever made, elevated with the performance of a tubeless system. The brand new Alpinist CL II now brings mountain-taming performance slightly closer to earth with a carefully selected build designed to let riders take full advantage of the low rim and spoke mass. The Alpinist CL II utilizes the same rim as the alpinist clx ii. They react to even the slightest increase in power with immediate acceleration and carve the purest lines in the corners, yet they can also handle almost double the impact standards of every certifying body. The result is a 1375-gram tubeless wheelset with an otherworldly ride quality designed for real-world road pressures. The Alpinist CL II utilizes components curated to keep you rolling and rolling fast. The DT Swiss 350 hubs, featuring their star ratchet drive system, are reliable and easy to service, while 24 DT Swiss comprace straight-pull spokes front and rear, laced to the rims with their alloy pro lock nipples, are synonymous with reliability and can be obtained at any bike shop. The reduced rolling resistance of a tubeless setup is undeniable, as are the benefits of improved handling and incredible puncture protection. It took the most extensive and demanding engineering and testing program we've ever undertaken.

The Arch MK4 is the wheelset a lot of us here at Stan's choose to ride. All-mountain, Downcountry, Trailduro—whatever they're calling it this week, when you like pushing your limits on climbs, descents, and every kind of trail, this is your wheelset. The Arch MK4's 28mm internal width and patented lightweight, low-profile design is not afraid to climb, while being an absolute monster on the descents. With a welded seam, reinforced spoke bed, and durable 6069 aluminum construction, the Arch MK4 rims give you the confidence to ride everything. When it comes to a consistent and reliable airtight tubeless seal, nothing beats Stan's patented Bead Socket Technology. The Arch MK4 rims feature an asymmetric design with offset spoke holes to improve spoke angle and create a stronger all-around wheel. Unlike most asymmetric rims that suffer from difficult inflation and poor tubeless performance, Stan's BST-Asymmetric design delivers all the advantages of a stronger wheel, with no compromises in tubeless performance. Nobody likes downtime, so the Arch MK4 wheelset is built with traditional J-bend spokes based on their proven strength, ride quality, and easy serviceability. Stan's has always made it easy to find replacement spokes should you ever damage your wheel, and now we've made it even easier. MK4 front and rear wheels of the same diameter all use the exact same very common spoke length, both sides, front and rear. Serviceability doesn't get any easier than that. From the first click of the incredible M-pulse hubs, it's clear that confidence is the philosophy behind every part of this wheelset. Designed and CNC machined by Project321 in Bend, Oregon, M-pulse freehubs feature 6 pawls with Neodymium magnets that lock into place with greater force than conventional pawl springs, but offer virtually no resistance when coasting. Multiple teeth on each pawl offer better load distribution for years of trouble-free riding, and the angle of the pawls was engineered to transfer stress away from the rotating bearings, decreasing stress and wear on the entire freehub. That durability extends to the 17mm axles machined of 7075 aluminum and the full complement of Enduro brand bearings, including a double-row freehub bearing. M-pulse internals are also fully shielded inside the hub, because the only thing better than a good bearing seal is a good bearing seal most dirt can't even reach. As durable as they are, these hubs are also built for speed. M-pulse hubs engage with only 1.66°of rotation, putting down power nearly instantaneously, but how smooth these hubs roll is what really stands out. Adjustable preload allows you to fine tune M-pulse hubs for reduced friction, and less drag means more speed on the ground.The result is a bombproof hub with quick, consistent engagement and less resistance for more speed. Available with Shimano Micro Spline, HG, or SRAM XDR freehub, and 6-bolt or Centerlock brake style, with options to fit all popular axle configurations. Tubeless ready with rim tape installed. The Arch MK4 is our most versatile wheelset, and the best aluminum wheelset available for riders who want to push limits on every trail. Up, down, and wherever the ride takes you, the Arch MK4 wheelset has it under control. - Arch MK4 wheels include pre-installed tape for tubeless use and presta valves. - Versatile 28mm internal rim width optimized for 2.2-2.5” tires - Light and durable 6069 aluminum with welded joint and reinforced spoke bed - BST-Asymmetric design combines Stan’s legendary easy tubeless inflation with a stronger, more balanced wheel build - M-pulse ultra-low drag magnetic pawl adjustable hubs with 1.66° engagement - Enduro bearings with double-row freehub bearing - Matched wheelsets use traditional J-bend lacing and share a single spoke length for easy serviceability - Connection program includes 5-year hub warranty, 3-year rim warranty, 1-year crash replacement, and $10 donation to trail maintenance or advocacy group of your choice
