No.9 36w rims are our choice for all-around trail riding and off-road touring. They fit a huge range of modern mountain bike tires, and offer lightweight performance across the board. Available in both 27.5” and 29” sizes, these highly-versatile mountain rims provide huge performance gains over aluminum rims of the same width. A perfect mix of width, weight and stiffness, these will be right at home on almost any mountain bike in your stable. As with all rims we sell, these come with tubeless valves and tape required in the box.
