- The Series 4 aluminum alloy frame features high end 3D forged rocker links and dropouts, paired with highly manipulated tubing, to create a rough and tumble long travel bike that is stiff, strong, and ready to take what the nastiest trails dish out.
- ALPINE TRAIL TECHNOLOGY -
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.
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.
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.
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.
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.

- WGWilliam G.Verified BuyerI recommend this productRated 5 stars5 months agoGreat Cross Country bike
I own a 2020 Marin Rift Zone carbon 2 and my new Marin Alpine XR is a great addition. As always Marin offers excellent bikes for an amazing bang for the buck. I highly recommend it and the incredible service from GovVelo.
- DDavidVerified BuyerI recommend this productRated 5 stars7 months agoGovVelo service
I did a lot of research so I knew the bike was the right one. I'm replacing my downhill bike, but wanted something that could climb as well. I expected the bike to show up in the Marin box, but much to my surprise GovVelo had built it up and repacked it. Grease on everything dropper connected. Nice great shop.
