Mavic Crossmax Pulse Tubeless Tire 27.5x2.1 BlackThe Mavic Crossmax Pulse Tire is essential for cross-country, so we’ve made the tire with an X-mix dual compound (55/50) so the softer side knobs give you the extra confidence to keep your cornering speed high. The 2.1" tire is also designed to work best on the Crossmax SL Pro rim, and the combination offers the ultimate mix of fast rolling and cornering grip. To save weight, Crossmax Pulse has no extra protection layer, but it doesn’t need it, as the casing is thick enough to stay robust and support you in any race or on any trail. And the UST Tubeless Ready casing (air tight with sealant) delivers weight saving, comfort, grip and traction as well as a reduced risk of flats. UST Tubeless Ready. Available in 27.5x2.1 and 29x2.1.887850550509
