Check out Large Marge. These black anodized, eyeleted, double-walled 24″ and 26″ hoops are 65mm wide. They feature machined sidewalls for those of you who may want to use rim brakes…Magura hydraulic rim brakes, traditional cantilevers, and linear-pull with 2.2–2.4″ tires (larger tires may interfere with the cross-over wire). The cross-sectional profile gives our rim incredible strength, while shedding snow and sand to keep the rotational mass as low as possible. We offer Large Marge in a number of configurations: 32-hole and 36-hole downhill rims are available in 24″ and 26″ sizes, and a 32-hole cruiser/cross country version is available in the 26″ size. What’s the difference between the cross-country and DH rims? The cross-country rim is machined, at its outer wall, to shave some grams. What’s the weight? The 26″ DH rim…1150 grams, the 26″ XC rim…1050 grams, and the 24″ DH rims…1050 grams. All are drilled for Presta (French) valves, but any bike shop can drill them out for use with Schrader (American) valves.
You’re going to need a fat-tire cruiser frameset, a DH-style frame and fork, or a non-standard XC frame and fork…like the Surly Pugsley…to use Large Marge rims. Most stock XC frames and forks simply don’t have the clearance for wide rims and fat rubber. Other options: Some custom builders will be happy to build a frame and fork for you. Or, you could chop the cantilever bosses from a 1×1 frame and fork or from an Instigator frame and fork, allowing the wide rim/tire combo to fit into the frame without brake boss interference. Depending on the make and model of tire, and the position of the wheel in the rear dropouts, 2.7–3.0″ tires will fit in the 1×1 frame. The Instigator can handle 2.6–2.7″ tires. For maximum traction and floatation, combine Large Marge Rims with Endomorph 3.7″ tires on a Pugsley frameset, all designed with one another in mind. Meaty beaty big and bouncy.
