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

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.
