41w rims are wide, light and versatile. The 35mm inner width is optimized for use with wide trail tires to plus sized tires. Opening up large volume tires, and supporting wide set cornering knobs make these perform. These provided noticeable stiffness differences over aluminum rims of this class, while cutting weight where you’ll notice it the most. With an optimal tire range of 2.4”-2.8"s, 41w’s are equally at home on short to mid travel mountain bikes, plus tire set ups, or off-road touring rigs.
