Blackthorn 145 Eagle 70 Transmission Bike - 29", Aluminum

The best all-mountain bikes perform on a wide variety of terrain and give you everything you need to thrive on rides where you’re out all day and don’t always know what to expect. Blackthorn 145 Eagle 70 Transmission was built for this. Its aluminum frame features a slack 63.9-degree head angle and short chainstays for stability and maneuverability when descending and navigating tech, with a steep 77.4-degree seat tube for comfortable seated pedaling when you’re climbing up to the next pass. Split Pivot suspension design allows us to optimize Blackthorn’s pedaling and braking performance independently, for better small bump compliance, braking traction, and pedaling efficiency. A RockShox Super Deluxe Select+ shock delivers 145mm of rear travel and a RockShox Lyrik fork gives you 160mm of travel to play with. Blackthorn’s cargo mounts make it easy to load up all the water, snacks, and kit you need for long days out. SRAM’s Eagle 70 Transmission drivetrain and Maven four-piston brakes give you precise control over your pace up and down the mountain.

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 145 riders can swap control and shock links, in addition to the rear shock and fork, to switch travel to Blackthorn 125's 125mm rear and 140 mm front capability. One frame, multiple bikes. Progressive leverage rate Blackthorn is designed with a progressive leverage rate that offers plenty of bottom out performance at the end of the stroke, promoting more confidence and control on bigger hits and a deeper feel to the travel. The beginning and mid-stroke provide extremely supple small bump compliance off the top for a smooth ride and consistent mid-travel support to help combat rider fatigue and maintain bike geometry. Purpose-tuned suspension Blackthorn-specific control link and shock links optimize the frame geometry and kinematics for its suspension travel, delivering a well-rounded, balanced trail feel. All-mountain geometry Blackthorn 145 is long, low, and slack, with a dash of moderation to preserve pedaling performance. A 63.9-degree head tube angle creates a long front center with the stability to descend loose, steep trails in total confidence, while a steep 77.4-degree seat tube angle makes seated pedaling and climbing more comfortable. Short 432–433mm chainstays keep Blackthorn agile for handling tight situations. Flip chip A flip chip allows a simple and quick 5mm adjustment to bottom bracket height and 0.3-degree adjustment to head tube angle to account for your personal preference, terrain, or wheel size and tire diameter. 6061-T6 aluminum frame Heat-treated aluminum frame for stiffness and durability. Top tube accessory mounts Top tube mounts accommodate direct-mount top tube bags or the K-Edge Top Tube Mount for bike computers. Fits two bottles on all sizes Stay hydrated on long trail rides with space for two bottles on all frame sizes. Integrated repair kit location Bring your multitool and tube without scuffing your frame or hauling around a hip pack. Versatile wheel and tire fit Blackthorn features clearance for up to 29 x 2.5" tires and is compatible with mixed wheel sizes. Coil shock compatibility Blackthorn is compatible with most coil shocks. Molded frame protection Molded rubber down tube, seat tube, chainstay, and seatstay guards protect your frame from impacts and abrasion. BK01051 - L Black Spruce
