Everyday Adventures

Urban Warrior
Out Of The Box Riding

The Marin Larkspur has all the looks of an old-school step-through but with chunky tanwall tires, wide rims, powerful disk brakes and the option of a dropper seat post. Beneath those old-school looks is a super modern and Marin Bikes-made steel frame and plenty of today’s standards to keep it right up to date.

Why just roll to the deli or ride to work when you can take a detour down your favourite dirt track on the way? It's an adventure bike, it's a gravel bike, it's a mountain bike, it's a commuter bike... it's whatever you want it to be.

The Marin Larkspur 1 is built around a Series 2 butted CrMo step-through frame, a curved CrMo fork and 27.5” wheels. It has high volume 2.35” Vee Tire Co tires, a microSHIFT 10-speed drivetrain, Tektro hydraulic brakes and plenty of reliable Marin components to complete the package.

Technology

Steel Frame

The Muirwoods uses a butted Series 1 4130 CrMo frame and fork with 29” tires, disc brakes, full fender and rack mounts, and two bottle bosses. The Muirwoods RC uses a double butted Series 2 CrMo rame with sliding dropouts for internally geared hub compatibility and large volume 650B wheels and tires. Larkspur models also feature the butted Series 2 frame with a mixte stepthru design for easy mounting and dismounting, even with baskets and baby seats.

Wide-Range 1x Drivetrains

Both Larkspur models are built around modern, wide-range drivetrains, 10-speed on the Larkspur 1 and 11-speed on the Larkspur 2. These drivetrains are stout and have all the gearing most anyone could use, without relying on sometimes-fussy front derailleurs. Clutch-type rear derailleurs and narrow-wide front chainrings keep the chain on track, all the time.

Disc Brakes

Hydraulic disc brakes provide smooth, controlled stopping in all conditions with minimal maintenance.
