San Anselmo DS4

(msrp: $799)
San Anselmo DS4 Matte Black w/Blue, Dark Silver, and Silver Graphics


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.
