The Cast Antagonist is the definitive choice for riders who push their limits on enduro and downhill tracks. Designed with a focus on maximum mechanical grip, the tread pattern features alternating centre blocks for consistent braking traction and reinforced shoulder knobs that bite deep into corners, providing a predictable feel even when the bike is leaned over at high angles.
At the heart of the tyre is the DualWall construction. This 2-ply casing significantly increases sidewall stiffness and puncture resistance compared to standard trail tyres. This design allows you to run lower pressures to maximise your contact patch without the risk of tyre squirm or pinch flats. The TLR (Tubeless Ready) bead ensures a secure, air-tight fit on modern wide-rim profiles, while the tacky rubber compound provides exceptional dampening over roots and rock gardens. Whether you are racing against the clock or lapping the bike park, the Antagonist is built to withstand the abuse of modern gravity riding.
DualWall Construction: A heavy-duty 2-ply casing provides superior impact protection and sidewall stability under high G-loads.
Aggressive Tread Design: Wide-spaced knobs shed mud effectively while providing biting edges for loose-over-hard conditions.
Tubeless Ready: Optimised bead hook design for easy inflation and a reliable seal with sealant.
Gravity-Focused Compound: Formulated for high slow-rebound properties, reducing "pinging" off rocks and improving rider control.
Size Versatility: Available in both 27.5" and 29" diameters to suit modern mixed-wheel (mullet) or dedicated wheel size setups.

Aggressive Descenders: You prioritise downhill grip and sidewall support over uphill rolling speed.
Puncture Prone Riders: If you frequently slash sidewalls or get pinch flats on lighter tyres, the DualWall protection is a game changer.
Bike Park Enthusiasts: Built to handle the repetitive high-speed impacts and berm-slapping forces of gravity-fed laps.
Mixed Conditions: The tread handles everything from dry, dusty summer trails to tacky autumnal dirt with confidence.
Weight Weenies: The reinforced casing adds significant weight compared to a lightweight XC or Trail tyre.
Tarmac Commuting: The soft compound and aggressive knobs will wear quickly and feel sluggish on paved surfaces.
Mellow Trails: On flat, non-technical terrain, the Antagonist offers more "tyre" than you likely need, making the bike feel less poppy.
If you are running a "Mullet" setup (29" front / 27.5" rear), try running the 29" Antagonist on the front for maximum steering precision and the 27.5" on the rear. Because the rear tyre takes the brunt of most square-edge hits, the DualWall casing is essential here to protect your rims. Always check your pressure with a digital gauge; because the DualWall casing is so stiff, it can "feel" firm even when the pressure is too low, so don't just rely on the thumb test!
