I am very satisfied with these ZLEEN tires! I ride with confidence and haven’t had any issues to report after more than a year of racing and training with these tires. The grip is insane! They are really excellent tires.

I tested Zleen in competition during a World Cup XCE round and was pleasantly surprised — the grip was excellent and the rolling efficiency very good too.

Love my Hawk — excellent grip on rocky southern-France enduro runs, survived comps and e-bike abuse. 5 + months in, zero punctures and still flawless.

Meet the Racerunner
The Racerunner — a lizard known for its incredible speed and agility. The master of navigating difficult terrains with remarkable ease. Be it a rugged land, rocky landscapes, gravel paths, and dense forest trails, the racerunner weaves effortlessly over the uneven ground zipping between rocks and roots faster than the eye can follow.
