The Podium Story
Where limits are tested.
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 pushing your performance with the Podium, these bikes are built with the same spirit: capable, purpose-driven, and ready for whatever lies ahead.
