WTB Course 52 Tubeless Gravel Tire (700c) (52mm) (Light/Fast Rolling) (Tan Wall) (Dual DNA/SG2)

WTB Course 52 Tubeless Gravel Tire Description:

The WTB Course 52 Tubeless Gravel Tire is a versatile high-performance tire with outstanding efficiency and comfort. Stromm Aerotech detailing on the leading edge of the side walls significantly reduces wind drag so it is easier to maintain speed and conserve valuable energy. A low profile tread design rolls easily on hardpacked surfaces and has enough biting edges to deliver predictable braking, cornering, and traction, and Dual DNA rubber compound compliments the performance of that tread pattern while simultaneously boosting the durability of the tire.

Supporting everything from the inside is a 120TPI TCS Light casing which produces a buttery smooth ride that floats over rougher surfaces, and SG2 puncture protection will fight off cuts and punctures with minimal impact on performance or ride quality. Last but not least, the WTB Course 52 Tubeless Gravel Tire is compatible with hookless, tubeless ready rims and is optimized for use with the wider rims found on modern gravel bikes, ensuring these tires have what it takes to briskly and safely get the rider anywhere they want to go.

Features:

• Large volume, smooth riding gravel tire with a versatile tread pattern and aerodynamic enhancements that make it easier to achieve and maintain higher speeds
• Stromm AeroTech uses vortex generators and trip strips at the leading edge of the tire sidewalls will control the boundary layer separation and manipulate the airflow as it goes around the tire/wheel system to reduce the low pressure wake that would usually increase drag
• Testing confirms drag reductions/energy savings at real riding speeds, with up to 6 watts saved at 19 mph, 9 watts at 25 mph, and 14 watts at 25 mph, just from the tire!
• Low profile central tread blocks are spaced closely together to reduce rolling resistance and produce a smoother ride, and the knob spacing and shape opens up to the sturdy shoulder knobs for confident and predictable cornering manners over variable road and trail conditions
• Fast rolling compound using Dual DNA construction places firmer tread compound down the center of the tire for better durability and low rolling resistance and a softer compound around the shoulder of the tire for enhanced traction
• TCS Light casing utilizes a thinner 120 TPI casing to minimize rotational weight and provide a very smooth and supple ride quality that also retains very good durability
• SG2 puncture-resistant nylon layer with bead-to-bead coverage offers significantly better cut and puncture protection than traditional single-ply tires and also provides excellent air retention without adding significant weight or impacting the ride quality
• WTB’s Tubeless Compatible System (TCS) design allows the rider to take advantage of the enhanced flat prevention, enhanced traction, and smooth ride that tubeless tires and rims provide, and this system is compatible with hookless rims
• Optimized for 25mm to 32mm internal width rims typically found on modern gravel bikes
• Tire is shipped in 100% recycled packaging as part of WTB’s efforts to reduce the environmental impact of manufacturing and shipping tires
