Tunnel Podium
Tunnel isn’t just a ride — it’s a challenge carved into the mountains above Santa Barbara. Rutted, raw, and relentlessly steep, it’s a trail that demands skill, commitment, and a bike built to deliver. It’s the kind of place that forges better riders — and better bikes. That ethos inspires the Stinner Tunnel line. Whether you’re just beginning your journey with the Select Series or pushing your performance with the Podium, these bikes are built with the same spirit: capable, purpose-driven, and ready for whatever lies ahead. Where it all begins. Where limits are tested.
