The Spank 350 Rim can withstand the rigors of all-mountain riding, yet there lightweight for instant responsiveness. The MGR Dynamal Alloy rims feature a wide 35mm outer width, with a 30.5mm inner width. The wider rim increases air volume, aids lateral support, and puts more tire tread in contact with the ground. The low sectional profile rim height and width adds radial compliance while keeping high lateral stiffness. The tubeless Bead Bite Hook on the rims prevents the dreaded "burping" of tubeless tires.
