Course TCS Tubeless Tire pairs Stromm aero sidewalls with SG2 protection
The Course TCS Tubeless Tire runs a 120tpi TCS Light/Fast Rolling casing with a tubeless folding bead, and SG2's three-piece nylon puncture layer spans bead to bead for flat protection without stiffening the ride. The Dual DNA compound splits the difference between a fast-rolling center and softer, grippier shoulder knobs, so cornering traction doesn't come at the cost of straight-line speed.
What Our Gearhead® Experts Are Saying:
"The Stromm aero shaping earns real numbers, not just marketing copy. WTB's own testing puts the drag savings at roughly 9 watts around 22mph, and I notice it most through long, exposed gravel sectors where I'm holding pace into a headwind."
