BIG ALL-MOUNTAIN DAYS WHERE TRAVEL AND GEOMETRY MATTER MOST
BUILT FOR ABUSE AND ROWDY RIDING
ENDURO-STYLE RIDING AND RACING
BIG BIKE, BIG WHEELS, BIG FUN
The Alpine Trail is a 29” wheeled full suspension bike built for the all day enduro rider that earns their downhill fun.
Key upgrades from Alpine Trail 7:
UNIDIRECTIONAL CARBON FIBER FRAME
Alpine Trail Carbon 1 and 2 models feature high modulus carbon fiber and monocoque construction to deliver the strongest and stiffest Alpine Trail to date.
Alpine Trail models feature Series 4 aluminum frames, with detailed forgings, highly manipulated tubes, and full internal cable routing, giving the rider the highest-end alloy frame that Marin offers.
ONE PIECE FORGED ROCKER
The heart of the Alpine Trail’s MultiTrac suspension is the forged one-piece rocker link. The strength and stiffness of the rocker keeps the rear of the bike tracking straight, providing smooth suspension operation under the most demanding conditions.
BRIDGELESS SEATSTAY
The stiffness of the one-piece rocker link allows for a bridgeless seatstay design, offering zero compromises on stiffness while at the same time allowing for maximum tire clearance and short chainstays.
MODERN ANGLES
The Alpine Trail has a slack 63.5º head tube angle paired with a steep 78º seat tube angle and long reach to provide the best modern trail bike experience. The bike lets you climb better than ever before, while giving you even more confidence when descending.
