IRC’s new Aspite clincher endurance racing road tires build in a little more protection than the Formula Pro models we’ve tested and liked. Their target was the Continental GP4000, but they wanted to come in more affordable.
The Aspite will come in two versions, one with “pebbles” of grip on the sides that get more dense as they roll off the edge, and the Wet version uses slanted lines to move the water out from under the tire.
They’re also aero…
A small flare creates a smoother transition from the tire to the rim, eliminating the usual inward curve that leaves the top of the rim exposed to oncoming air. They’re claiming a 4% drag reduction compared the GP4000.
Available in 700×24 (205g) and 700×26 (245g).
The Formula Pro Tubeless gets a new 25c width on the RBCC version…
…and this prototype 28c size was spotted in Stan’s booth.
The Serac CX Mud is a new version of their cyclocross tires for muckier conditions. It’s tubeless like the original, but with a more open, paddle like tread shape. Weight is 380g.
The mountain bike tires get 27.5″ options for most all of their treads.
