The 2016 Altamont features a new tubeless rim bed profile with a bead locking shape. Run tubeless road wheels at high pressures, or even cross tubeless clinchers at low pressures. The rim bed is designed to lock the tire beads into place and prevent burping the tire. The wide center channel allows for side by side bead mounting (not stacked like with a narrow rounded center channel). This makes for much easier mounting and inflation; no more breaking tire levers and relying on an air compressor for inflation!!
Of course, clincher tube and tire systems work perfectly with the new Altamonts. If you are not running tubeless, your favorite tire can still be used flawlessly.
