Technical Specifications

Performance on the Trail

The CTK1 OTF’s 3‑inch drop‑point design creates a larger contact patch, delivering exceptional grip on loose soil, mud, and rocky sections. The strategic placement of high‑volume knobs improves self‑cleaning, ensuring consistent traction even after prolonged rides.

Thanks to its OTF tubeless system, riders experience a smoother ride with lower rolling resistance, which translates into better energy transfer and longer ride distances. The reinforced sidewalls resist cuts and abrasions, making the tire resilient against the toughest off‑road challenges.

Installation & Maintenance Tips

1. Check rim compatibility – the CTK1 OTF fits standard 700c MTB rims with a 2.25‑2.40" width.
2. For tubeless setup, apply the supplied sealant evenly across the interior of the tire.
3. Inflate to the recommended pressure (30‑45 psi) depending on terrain and rider weight.
4. Periodically inspect the tread and sidewalls for cuts or embedded debris.
5. Re‑apply sealant every 2‑3 months to maintain optimal puncture protection.
