Marin Alpine Trail XR
Details
Big mountains, epic passes, and all-day ripping descents. If you live for the alpine adventure and gravity-fueled downhills, look no further than the Alpine Trail series. Updated for 2021, the Alpine Trail is built around the longest travel version of our critically acclaimed MultiTrac platform with progressive slack headtube/steep seattube geometry, low-slung aluminum frames, and 29" wheels. The Alpine Trail is here to conquer all singletrack in its path.
Series 4 Aluminum Frame
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.
- Series 4 Aluminum Frame
- RockShox Lyric Ultimate 160mm fork
- Rock Shox Super Deluxe Coil Ultimate RCT shock
- Shimano SLX 1x12 drivetrain
- X-Fusion Manic dropper post
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
