Fast, Fun, and Ready for the North

The 2025 Marin Rift Zone 1 29 is the kind of bike that punches above its weight—whether you're sessioning Sudbury singletrack, chasing KOMs, or just outrunning your buddies for post-ride snacks. Built around Marin’s Series 3 aluminum MultiTrac frame, this trail machine delivers 130mm of plush rear travel paired with a 140mm fork up front—ideal for everything from local loops to big backcountry epics.

29” wheels keep the momentum rolling through roots and rock gardens, while a modern trail geometry gives you the confidence to send it when things get steep or spicy. The Rift Zone 1 hits the sweet spot for riders who want trail capability without the boutique price tag. This is a bike you can ride hard right out of the box—and keep upgrading over time.

We love how serviceable this build is too. Easy to work on, reliable components, and no nonsense. It's a perfect choice for new riders or seasoned weekend warriors who want a real-deal trail bike that won’t ghost you when things get rough.
