Bike Description

The San Anselmo DS4 is the ultimate traveling partner, whether it’s a weekend excursion or year-long journey. The lightweight hydroformed aluminum frame features full rack and fender mounts for accessories as well as our Women’s Fit Dual Sport geometry, which is designed to offer stable handling regardless of terrain. A Suntour NCXD fork with hydraulic lockout offers plush control in the rough while being able to roll fast for pavement riding. A full compliment of Shimano components are used, including stellar M395 hydraulic disc brakes as well as a Deore & Altus drivetrain.

Bike Features

Hydro II Tubing

Hydro II Tubing

Hydroformed 6061 aluminum-alloy frame tubing engineered to tune the flex properties of a frame with high precision, providing stiffness or flex exactly where desired and maximizing frame performance. Hydro II is our second generation engineered shape tubeset which provides lighter weight tubing with similar strength and ride qualities as the previous generation.

Women’s Fit Geometry

Women's Fit Geometry (WFG) models are designed around a women's body with shorter reach and women's specific saddles, grips and other component choices.
