WALDEN TI - BUILT FOR THE BACKCOUNTRY

Durability

Titanium is as durable as it comes, providing anti-corrosive qualities that deliver a trusted ride in every season.
All Esker frames are over-engineered to withstand far more than a normal ride using proven materials, and testing beyond the limits to ensure you get all your miles in and out - wherever you may go.

Geometry

At Esker Cycles, we promise intentional design that lets you go farther with less fatigue. Walden Ti encourages you to traverse a coastline, desert or tundra with confidence and ease. Thanks to a slightly less slack headtube angle, you’ll experience more precise steering and control at high speeds.

Ride Quality

Walden Ti is optimized for success in soft sand, snow, hardpack and washboard with added comfort to go the distance. The titanium frame soaks up even the most subtle vibration - ensuring you’ll arrive back at camp with plenty of energy for the next day’s adventures.
