Velocity - Blunt35 Disc Rim (silver)Designed as a wide, tubeless compatible, mountain rim option, the '35' part is a reference to its astounding width, which gives any wheel built with it a larger footprint with more traction. Very useful for cross country and all mountain riders who are looking for lateral stiffness without so much weight. We like to put 2" to 2. 6" tires on this rim, and we like to use it to test the limits and to see where we can ride.
