Details
Blackthorn C XTR comes equipped for challenging all-mountain terrain. The carbon fiber frame lends the stiffness you need to hold your line. The 140 mm Fox Float X Factory shock and 160 mm Fox Float 36 Factory GRIP2 fork ensure that you can handle just about any feature that's waiting around the next berm. Progressive geometry and our Split Pivot suspension design keep things composed on wicked descents and put you in a position to overcome tough climbs. Our pack-free riding features include a padded tube strap spot, top tube mount, and bottle mount for a lighter load on your back.
Shimano's gold-standard XTR 1 x 12 groupset and four-piston brakes make speed modulation as smooth as it gets. All told, we think it's the best all-mountain bike out there—we invite you to see for yourself.
KEY FEATURES:
SPLIT PIVOT® REAR SUSPENSION SYSTEM:
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 / Incredible pedaling efficiency / Smooth and predictable braking throughout travel / Maximum traction.
SPLIT PIVOT +
Split Pivot + is our suspension development philosophy that allows riders to swap suspension travel within a single chassis.
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 rider’s 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.
MULLET BUILD COMPATIBILITY
Mullet build compatibility lets riders run a 29" wheel in the front and a 27.5" wheel in the back with minimal impacts to geometry.
CHAIN GUIDE-COMPATIBLE
Blackthorn frames feature 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.
