The Rock Spring 1 is built to go explore cross country singletrack and fire trails or as a durable do it all bike for a commuter.

The Rock Spring 1 is built around a durable, lightweight 6061 aluminium frame and Marin’s size specific wheel size system. Each frame size is paired with the wheel size that best fits the rider and sets them up for optimal efficiency and power transfer. It's simply logical to pair 29" wheels with larger bikes, and more proportional, better-fitting 27.5" wheels for smaller bikes.

The trickle down technology of higher end bikes such as disc brakes is evident on the Rock Spring 1. The advantages of disc brakes can't be understated on a mountain bike. Tektro M275 hydraulic disc brakes not only improve power and modulation but they provide consistent braking in all conditions. Combined with an SR Suntour XCE with 100mm of travel and 24 Speed Shimano drivetrain, the Rock Spring is built to handle off road trails.

What really sets the Rock Spring 1 apart from other entry level hardtails is the geometry. A steeper 74 degree seat angle, improves climbing efficiency, positioning you in a more upright, comfortable position. While the slack head angle of 68 degrees, short 45mm stem and wide 780mm bars, improves stability at speed and confidence when descending. Often understated is benefit of a low standover. The Rock Spring has one of the lowest standover measurements in the category, making the bike easier to handle for smaller riders, while making it easy to mount and dismount.

If you are looking for a do it all bike, that is up to date with all the current trends and is trail ready at an affordable price than the Rock Spring 1 is for you.
