From smooth XC cruisers to full-on downhill tracks, Marin’s Attack Trail 9 is your means of crushing it all. Its carbon monocoque front triangle delivers rock-solid rigidity and time-to-get-zesty responsiveness, while a custom-tuned BOS Kirk shock tames 150mm of travel that swallows trail obstacles whole. Your advantage becomes clear when a BOS Deville AM fork tags into the match with 160mm of sensitive, high-performance travel giving you the control to absolutely charge. Whatever the mountain throws your way, mash the pedals through the formidable carbon X01 crankset that motors SRAM’s XO1 1 x 11-speed drivetrain, spinning up DT Swiss E1700 27.5-inch wheels wrapped in enduro-approved WTB Breakout and Vigilante tires. A shred-ready KS LEV Integra dropper post lets you roll seamlessly from harrowing descent to steadfast climb and back down again with ideal saddle height at every stretch. And to reel it all in, just a tap on the SRAM Guide brakes keeps you slashing apexes and hitting the transitions.
