Mountain Frames

The Blackthorn C frame blends a stiff carbon fiber chassis with our progressive trail geometry and Split Pivot suspension design. The result is a well-balanced platform for an all-mountain bike that descends with gusto, rails through features, and makes climbing up for lap two as painless as possible. The Fox Float X Factory shock delivers 140 mm of travel to guide you through whatever the trail serves up. On-bike cargo features hold your tube, pump, and repair kit, and more on the frame to lighten up your hip pack—or allow you to ride pack-free. We made Blackthorn C the best all-mountain bike frame around. Take it and make it your dream bike.

Build it up and go big.

The Salsa Heyday! C Deore 12 is a carbon fat-tire bike with the versatility to go wherever your imagination takes you.

A mind-blowing number of cargo and accessory mounts let you bring more than just the bare necessities, and Mukluk's geometry ensures a stable ride even when loaded. Alternator 2.0 dropouts allow for multiple drivetrain options, but the stock Shimano Deore 12-speed is the perfect place to start.
