Rims

Designed with input from Stan's Enduro World Series teams, the new Arch MK3 is ready to own every trail. WideRight optimized for maximum stability with 2.25-inch to 2.5-inch tires, Stan's expanded the internal width out to 26mm while keeping the rim incredibly light. The 27.5-inch 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. - The perfect balance of strength and weight - 24% wider than the Arch EX for improved stability with larger tires - Same light weight as the Arch EX - Low-profile shape rolls faster, lasts longer, and helps stop tire pinch flats - 25% stiffer and stronger for improved handling - Lighter and more durable rim shape and alloy - Most trusted tubeless system for easy setup and low maintenance - WideRight optimized for Trail tires

Wheels are the first point of contact between you and your bike, and the trail you’re riding on. And while wheel sizes and standards continue to develop significantly year on year, often to both the rider and the industry’s dismay, very little innovation has been seen in the compliancy and responsiveness of the wheel as this first, most important contact and conductor. What Spank has seen in recent years is that bike suspension is continuously evolving and adapting to compensate for stiffer frames and more rigid, deeper profile carbon fiber rims. This overall stiffer rig is being softened, or counter-acted by both bike suspension, and tire design — not to mention the ever lower and lower tire pressures riders are running. Rider position (wider, lower, more forward) is also being impacted directly by the bike frame and cockpit geometries which is constantly aiming for a better riding feel. So surely it is overdue time to re-examine how the engineering of the wheel can become an active contributor to the efficiency of the overall set up. Spank Industries has done just this. - Low sectional profile height and wide width, adds radial compliance, while keeping high lateral stiffness. - 30mm internal width extremely versatile, fitting tires from 2.0” to 2.6” perfectly, and even allowing + size tire use, without negative squaring off of tire profiles. - Ideal for Trail/AM/Enduro bikes looking for a wide profile, without the weight penalty

A 30mm welded Enduro rim developed for the fastest EWS rider. Enduro may be young as a discipline, but at its core is the intrinsic need of riders to ride burlier terrain faster and faster. Something that MTB has been all about since the beginning. The EX 511 rim is the perfect tool for this quest. It comes with all the technology that has delivered many EWS wins and packs it in a 30mm-wide profile, ready to go burlier, faster.
