The World’s First True Radial Bicycle Tire
Radial. Revolutionary. Radical.
Zleen Unveils the Racerunner Radical: The World’s First True Radial Bicycle Tire
Zleen sets a new benchmark in cycling performance with the official launch of the Racerunner Radical, the first-ever true radial bicycle tire. Debuting at the Eurobike Show in Frankfurt, this bold innovation redefines what riders can expect from traction, speed, and durability.
Radical Technology. Game-Changing Results. At the heart of the Racerunner Radical lies Zleen’s pioneering 88° true radial casing — a decisive break from the traditional bias-ply construction. This engineering leap unlocks a set of extraordinary benefits:
Designed with a slim profile and wide tread zone, the Racerunner Radical features a uniquely shaped cross-section that offers superior resistance to cuts and snakebites. Integrated bead-to-bead fabric protection ensures riders stay fast and fearless — whatever the terrain.
Inspired by Nature. Built for Speed. The Racerunner Radical is more than a tire; it’s a revolution in cycling technology. Drawing from natural principles of efficiency and Zleen’s unmatched manufacturing prowess, it delivers peak performance for riders who demand the future — now.
Experience Radical. Ride Zleen. Visit us at EUROBIKE 2025, Hall 12.1 Booth A08, for an exclusive first look and feel of what it means to ride truly radial.

Zleen Puma Pro Tubeless and Zleen Puma Race—New Tire for Muddy Terrain
The non-directional wet & muddy tire. This narrow XCM wet and mud expert is designed specifically for moist, rainy weather when self-cleaning and clearance between the tire and frame matter most. Avoiding the tires wrapped in sticky mud rubbing the fork and frame is what sorts out the winners to stand out from the crowd. The rough pattern gives Puma exceptional grip and traction.
Available as well in the Zleen Race range—tires developed exclusively for competitive riders. Benefiting from collaboration with prominent Elite riders, the Zleen Factory Race tires’ design is centered around unparalleled performance at race-grade conditions. Featuring the unique soft race compound and lightweight.
