HED's entire line of Big Deal fat rims can be purchased as a rim-only for the custom build of your dreams! Big Deal is 445 grams and 85mm-wide of pure fat-bike joy. This one-piece, full-carbon rim will change the way you ride. Big Deal utilizes a ribbed, single-wall design to maximize stiffness and minimize rotational weight…all on a tubeless-ready platform. Compared to most aluminum fat bike wheel/tire combinations in the market today, you can expect to lose 1.5 to 2 pounds… per wheel. Note that the Big Deal is drilled symmetrically ONLY and cannot accommodate offset frames. Big Deal utilizes Inflatobam, HED's patented tubeless technology for installing big tires. The twin channel rim design provides a better pre-inflation seal by trapping each tire bead against the rim. This drastically reduces the amount of air it takes to get the beads to “bam” into place. In conjunction with the rim shape, Inflatobam utilizes Inflatobands. These effectively provide a variable rim-channel diameter. This compensates for the discrepancies in tire bead diameters by minimizing the gap between the tire and the rim channels (the main source of air leaks). Once seated, the angled bead shelf prevents the tire from collapsing back into the rim at low pressure. Our interior surfacing and tight tolerances ensure no tire burp or slip. Also note that our rim shape does not require tire levers to remove and install tires. Inner tubes may be used, too. Additional Info - Rim Type: 85mm - Rim Material: Carbon - Rim Weight: 445g - Color: Twill Weave - Rim Hole Count: 32 - Drill Pattern: Symmetrical Only - Decal Type: White - MIN/MAX TIRE SIZE: 3.8 - 5.0" - Rim ERD: 564 (includes washer)

- Light enough to take XC racing but was born from research and testing on the Enduro World Series circuit, making it a great rim for anyone looking to improve both descending and climbing - Asymmetric rim design allows for a stronger wheel while offering the easy inflation and Stan's trademark unmatched airtight seal. - 28mm internal width ideal for 2.2-2.5" tires - Light and durable 6069 aluminum with welded joint and reinforced spoke bed

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
