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.
