Zleen's Mission: Top Performance Doesn't Have to Be Pricey
Zleen has made it its mission to make first-class tyre technology accessible to every cyclist. The brand firmly believes that the best tyres do not have to be prohibitively expensive and works hard to bring high-performance yet affordable tyres to the market.
Radial. Revolutionary. Radical. – The Future of the Tyre
With the Racerunner Radical, Zleen introduces the world's first-ever true radial bicycle tyre. This pioneering technology breaks from traditional bias-ply construction, using Zleen's proprietary 88° true radial casing. The benefits are extraordinary: a 30% larger contact patch for unmatched grip, the ability to use 70% higher inflation pressure to slash rolling resistance by 40%, and a 25% weight reduction to just 550 grams. Its uniquely shaped cross-section with integrated bead-to-bead fabric protection also offers superior resistance to cuts and snakebites.
Where are Zleen tires from?
Zleen is a European brand with its headquarters in Prague, Czech Republic. The brand combines European design and R&D know-how with the decades of experience and the state-of-the-art, high-quality production facilities of one of India's largest tyre producers to create innovative tyres for demanding riders.
Who rides Zleen Tires?
Zleen tyres are designed for ambitious cyclists, from daily commuters to competitive professionals. Specific technologies like the Soft Race Compound (SRC) were originally developed for "Factory Race Elite" tyres and are now featured in the Zleen Pro range, bringing elite-level traction to competitive riders.
Soft Race Compound (SRC)
Engineered for peak performance, SRC is an ultra-soft 47 ShA compound that delivers race-proven grip with a near “tire-to-ground” adhesive feel. It excels under extreme braking, aggressive cornering, and demanding climbs over steep or rocky terrain.
Dual Compound (DC)
The Dual Compound technology combines a high-performance 57 ShA centerline compound with a softer 47 ShA shoulder, delivering the perfect balance of durability and grip. The soft edges provide exceptional traction in tight corners and on loose, rocky, or muddy terrains, while the centerline ensures extended tire life.
Silica Compound (SC)
Crafted for Pro-level performance, this enhanced 57 ShA silica blend strikes the perfect balance—delivering exceptional grip while minimizing rolling resistance on paved surfaces. SC is the go-to choice for road riders chasing peak efficiency and precision.
Optimal Compound (O)
Purpose-built for city roads, touring, and daily commuting, the Optimal Compound delivers exceptional longevity with impressively low rolling resistance. Engineered for efficiency and durability, it keeps you moving mile after mile—reliably, smoothly, and with minimal wear.
Classic Compound (C)
A trusted all-rounder, the Classic Compound offers reliable durability and consistent performance for everyday riding. Designed for versatility, it’s the go-to choice for riders seeking a long-lasting, no-fuss solution across varied conditions and terrains.
Highly Elastic (HE) & Reclaimed Compound (RC)
Designed as under-tread protection layers (2mm or 5mm) for city-grade tires, both HE and RC compounds defend against punctures where it matters most. The blue HE compound adds a 2 mm layer of resilience for the eReady specifications. Meanwhile, the 5mm green RC for the eReady 50 specifications delivers solid protection—perfect for durable, budget-conscious urban mobility.
Tubeless Ready (TR)
Engineered for a flawless, airtight fit, TR tyres feature precision-shaped beads that lock securely into the rim. For peak performance, add a dose of Zleen Seal Pro tire sealant.
Apex Sidewall Reinforcement
A precision-engineered sidewall insert positioned just above the bead. It protects against pinch flats and rock strikes, absorbing brutal hits during aggressive descents and steep drops.
Bead-to-Bead (B2B) Fabric Reinforcement
A robust fabric layer running from one bead to the other, creating a strong barrier against punctures from sharp rocks, thorns, or glass. This is a hallmark of Zleen Pro tires.
DH — Downhill Spec
For extreme durability, the DH Spec features a dual-ply casing with an added body ply for maximum resistance to impacts and cuts. These tires are built to withstand sharp rocks and deep drops on the toughest downhill trails.
Aramid (A) & Reinforced Aramid (AR) Foldable Bead
This technology features a high-tensile, lightweight foldable bead. The AR (Reinforced Aramid) specification takes durability up a notch, offering enhanced safety, especially in heavy-duty applications.
120 TPI & 60 TPI Casing
The 120 TPI (threads per inch) casing offers a pro-level, highly-elastic construction for exceptional steering response and grip, making it ideal for racers. The 60 TPI casing strikes the perfect balance between lightweight and durability for recreational riders and hobby athletes.
eReady & eReady 5
Specifically built for e-bikes. The `eReady` specification features a 2mm HD under-tread layer for enhanced durability to handle the added weight and acceleration forces. The `eReady 5` spec uses a 5mm RC under-tread for maximum puncture protection while reducing rolling resistance to extend battery life.
HiVis Reflex & Black Neon Reflective Tape
The `HiVis Reflex` sidewall offers the widest reflective area possible for maximum visibility. The `Black Neon` is a state-of-the-art 10mm wide tape that is nearly invisible by day but reflects light in all directions (360°) at night.
