2024 Salsa Blackthorn Alloy Frame
SalsaWe know you have a "dream build" list hidden away somewhere. Nows the time to bring it to life on the Blackthorn Aluminum frame. This versatile all-mountain bike frame comes with a RockShox Super Deluxe Select + shock for 140 mm of rear travel. Our tried-and-true Split Pivot suspension design offers a supple, supportive ride with incredible pedaling efficiency so you can take on a huge variety of trails. Start with the best all-mountain bike frame out there, hang your favorite components on it, and let it rip.
Flip Chip
Make easy ride adjustments. Our flip chips alter bottom bracket height and head tube angle to suit rider preference, terrain, or wheel size.
Suspension Kinematics
Enjoy a familiar suspension feel. Our kinematics are tuned for each bikes purpose but share core priorities across the entire lineup.
On-Bike Storage
Carry more on your bike and less on your body. Our frames and forks feature mounts for extra bottles, camping gear, and ride accessories.
Frame Protection
Worry less about bike damage. Our frames and forks are designed and built to hold up to the rugged adventures you put them through.
Split Pivot Suspension System
Ride up and downhill efficiently. Our suspension system isolates pedaling forces from braking forces, so we can tune for both independently.
Split Pivot +
Choose your bikes suspension travel. Our design methodology allows us to optimize a frame for more than one travel class.
SPLIT PIVOT REAR SUSPENSION
Split Pivot provides a host of impressive suspension characteristics because the system isolates pedaling forces and braking forces from each other, allowing us to tune and optimize the bike for both independently. The concentric rear axle pivot, in conjunction with precise wheel link, brake link, and control link placement, results in excellent bump compliance and pedaling efficiency, smooth and predictable braking throughout travel, and maximum traction
SPLIT PIVOT+ DESIGN METHODOLOGY
The Split Pivot+ design methodology allows our engineers to optimize a frame for more than one travel class. This means that Blackthorn riders can swap control and shock links, in addition to the rear shock and fork, to switch travel to Cassidys 165 mm rear and 180 mm front capability. One frame, multiple bikes
PURPOSE-TUNED SUSPENSION
The Blackthorn-specific control link and shock links optimize the frame geometry and kinematics for its suspension travel, delivering a well-rounded, balanced trail feel
PROGRESSIVE GEOMETRY
Blackthorn is long, low, and slack, with a dash of moderation to preserve pedaling performance. A 64.6-degree head tube angle and short-offset fork feel confident when descending loose, steep trails or blasting through rock gardens. A steep 76.5-degree seat tube angle and consistent cockpit sizing makes for a comfortable pedaling position, while the moderate bottom bracket height provides stability at speed without sacrificing pedaling performance in technical sections. The long front center provides stability in extreme terrain while the short 432 mm chainstays make for nimble handling in tight situations
FLIP CHIP 2.0
Integrated into the shock link mount, Flip Chip 2.0 allows simple, quick adjustments to bottom bracket height and head tube angle to account for the riders personal preference, terrain, or wheel size and tire diameter
EPS CARBON MAIN TRIANGLE WITH CARBON SEATSTAYS AND ALUMINUM CHAINSTAYS
EPS construction allows for greater manufacturing control, smooth surfacing, a simplified bottom bracket junction, and an integrated shock mount. Carbon fiber material offers improved stiffness, better vibration damping, excellent toughness and weight savings compared to other materials. 6066-T6 aluminum heat-treated chainstays add durability
TOP TUBE ACCESSORY MOUNTS
Top tube mounts accommodate K-Edge Top Tube Mount for bike computers or the Salsa EXP Series Direct Mount Top Tube Bag
DOWN TUBE THREE-PACK MOUNTS
Three-Pack mounts on down tube accommodate a large water bottle on the lower pair and a frame-mounted pump bracket on the upper pair
INTEGRATED REPAIR KIT LOCATION
Located in front of the rear shock in the front triangle, we provide a dedicated place for a small repair kit, tube, or bag of gummies. No more loading up your pockets or strapping the essentials to random spots on the frame and damaging the frame finish. Carbon frames feature an integrated reinforced slot and frame protection. Aluminum frames feature a machined strap slot. The slot is sized to accommodate most 3/4"- to 1"-wide straps. A Salsa Tube Strap is included with each frame (Salsa Tube Straps are for use with tubes only)
ACCOMMODATES A 26 OZ BOTTLE
All Blackthorn sizes accept a standard 26 oz water bottle within the front triangle
INTERNAL SLEEVED CABLE ROUTING
Internal tubes guide housing through the frame, simplifying setup and maintenance, and creating a clean bike profile
MOLDED FRAME PROTECTION
Molded rubber down tube, seat tube, chainstay, and seatstay guards protect your frame from impacts and abrasion
VERSATILE TIRE FIT
Specd as a 29er, Blackthorn is also capable of running 27.5 x 2.8-3.0" wheels and tires
CHAIN GUIDE-COMPATIBLE
Blackthorn frames features ISCG-05 mounts for chain guides (removable on carbon frames)
STEALTH DROPPER POST ROUTING
Compatible with 30.9mm dropper posts for true trail bike performance
REMOTE LOCKOUT READY
Blackthorn comes equipped for remote lockout, with cable routing to the rear shock via a cable port on the drive side of the downtube that exits between the forward shock mounting plates. If adding remote lockout, use a double-width frame plug on the downtube and a single-width frame plug at the forward shock mount. These are available in the Salsa Thick Frame Plugs for Internal Cable Routing kit (QBP part #FS2366).
