The Select 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 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.

140 mm Travel

The perfect amount of travel to make the Tunnel capable of hitting almost every line you can find.

SRAM Eagle 90

Cable-actuated, full mount rear derailleur for worry free mechanical shifting on the trail.

29×2.5" Tires

Plenty of tire clearance means the Tunnel is ready to tackle just about anything you can throw at it.
