Marin Bolinas Ridge 2

The Marin Bolinas Ridge 2 is built for riders ready to explore beyond the pavement. Whether it’s your first singletrack ride or a daily fitness spin, this capable aluminum hardtail delivers confident control, smooth handling, and durability that invites you to ride more trails, more often.

With reliable Shimano shifting, hydraulic disc brakes, and Marin’s trail geometry, the Bolinas Ridge 2 turns every ride into an adventure.

Durable, Lightweight Aluminum Frame

At the heart of the Bolinas Ridge 2 is a Series 1 6061 aluminum frame, designed for all-around performance and everyday durability. The frame’s low standover height improves confidence and control on technical terrain, while the 68mm bottom bracket shell and 135mm forged dropouts keep things stable and strong under pressure.

The chainstay-mounted disc brakes provide a clean, efficient setup that improves braking performance and simplifies maintenance. Available with 27.5” or 29” wheels, the Bolinas Ridge 2 fits a wide range of riders and riding styles.

Smooth, Confident Suspension

The SR Suntour XCM DS fork delivers 100mm of travel to absorb roots, rocks, and trail chatter, providing a smooth and controlled ride on mixed terrain. A preload adjustment lets you fine-tune the fork’s feel for your weight and riding style, while the 46mm offset helps maintain balanced steering and stable control through corners and descents.

Strong, Reliable Wheels

The Marin double-wall alloy rims are lightweight yet tough enough for rugged trails. Paired with forged alloy 32-hole hubs front and rear, this wheelset is designed to roll smooth and stay true, mile after mile.

Grippy 27.5” or 29x2.25” MTB tires offer confident traction across dirt, gravel, and roots, keeping your ride predictable and fun wherever the trail leads.

Simple and Dependable Shimano 1x8 Drivetrain

Shifting is simple and intuitive with the Shimano 1x8-speed drivetrain, giving you everything you need for climbing and descending without the clutter of a front derailleur. The Shimano Altus shifter pairs seamlessly with the Shimano Essa rear derailleur, providing crisp, reliable gear changes.

A 32T alloy crankset with a steel narrow-wide chainring keeps your chain secure on rough terrain, while the 11–45T cassette offers a wide range for tackling steep climbs and fast flats. The sealed cartridge bottom bracket and KMC Z8 chain ensure long-lasting reliability.

Hydraulic Braking Confidence

The Bolinas Ridge 2 features Tektro M280 hydraulic disc brakes with 160mm rotors for powerful, consistent stopping performance in any weather. Whether you’re navigating steep descents or weaving through city streets, these brakes deliver smooth, predictable control that builds rider confidence.

Trail-Tuned Cockpit and Touchpoints

Comfort and control come standard with Marin’s thoughtfully designed cockpit. The Marin 31.8mm riser handlebar offers a 780mm width for confident steering and leverage (740mm on XS/S sizes for an ergonomic fit).

The Marin Alloy 45mm stem provides quick, responsive handling, while Marin MTB closed-end grips deliver a secure hold on bumpy trails.

A Marin Alloy 27.2mm seatpost and Marin MTB saddle keep you comfortable for long rides, and nylon platform pedals ensure a stable, grippy connection between you and the bike.

Built for New Adventures

The Bolinas Ridge 2 isn’t just a bike — it’s a gateway to new trails and experiences. Its durable build and confidence-inspiring geometry make it perfect for new riders, returning cyclists, and anyone seeking adventure on two wheels.

From local park loops to your first singletrack session, the Bolinas Ridge 2 offers the comfort, control, and capability to grow your skills and expand your horizons.
