Stans No Tubes Arch MK3 26-inch Rims
Brand | Stans No Tubes |

Designed with input from our Enduro World Series teams, the new Arch MK3 is ready to own every trail. WideRight optimized for maximum stability with 2.25" to 2.5" tires, we expanded the internal width out to 26mm while keeping the rim incredibly light. The 27.5" Arch MK3 weighs only 425g. A new proprietary alloy and stronger, low-profile rim shape means the new Arch MK3 is built to last. Featuring Bead Socket Technology, the new Arch MK3 also offers the unmatched traction, control, and reliability only found on genuine Stan's NoTubes rims.
Technology
Stan's No Tubes Bead Socket Technology (BST)
Bead Socket Technology rims are designed to match the shape of your tire's bead to create a safer and more secure air tight interface. Unlike the secure “socket” of a BST design, conventional rim shapes drive the bead of the tire down deeper into the rim, putting pressure on sidewalls that causes friction, restricts tire volume, and keeps the interface from forming a sufficient seal for tubeless use. BST rims secure the bead of the tire, not the sidewall, creating an air tight seal while allowing the tire's sidewall to expand to its true, rounder, more effective profile. The result is more traction and less rolling resistance. With lower-profile, less vulnerable sidewalls, our BST rims are also lighter and stronger by design, and accelerate more quickly.
Stan's No Tubes WideRight Rim Design
The most important piece to the bicycle-terrain interaction is the contact patch between the tire and terrain, so tire profile and tire pressure play huge roles in bicycle performance and overall handling. But many rims just don't work well with the tires we're all using. Rims that are too narrow fail to offer sufficient sidewall support and protection to your tires and create a less stable shape. The result is less control in the corners, less traction on climbs, and more rolling resistance. Rims that are too wide also distort the tire profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tire's volume. Our WideRight rim widths are designed to strike the perfect balance between tire volume and sidewall function.
The Lightbulb.
Too narrow. Tire is constricted, robbing traction and cornering stability.
The Bell.
Too wide. Tire beads are pushed wide, deforming intended tire shape and tread design. Tire has less ability to absorb impacts and less cornering control, and sidewalls are exposed to cuts.
WideRight.
The perfect width. Tire expands to full volume without distortion. Tread pattern and side knobs are in the correct position for cornering, maximum traction and control with minimum rolling resistance.
WideRight rim profiles allow the tire to achieve its proper shape, and that's the foundation for a great handling, fast-rolling, and responsive bike.
Stan's WideRight system makes it easy to find the perfect rim width for the tire size and volume you ride. Too narrow of an internal rim mixed with a high sidewall design gives you a "light bulb" tire profile while an ultra wide rim on a narrower tire will give you a flat to "bell shaped" tire profile. Neither of these scenarios give optimal tire profiles nor allows the tire to perform as intended.
WideRight profiles provide the optimal volume without distorting the tread pattern or the side knobs so each part of the tire is in the correct position for rolling and cornering, allowing for maximum traction and control as well as offering minimal rolling resistance. The WideRight profile advantages don't stop there. Proper tire profiles not only allow for optimal tire performance but also allow the tire to do its secondary job of protecting the rim as well as the tire's sidewall. A flat or bell-shaped tire profile leaves the tire exposed to sidewall cuts and creates undue chances for rim damage.
