The All-New Marin Alpine Trail Carbon has Landed

Date Dec 10, 2020

If you were to draw your dream mountain bike, it might just look something like the new Alpine Trail Carbon. It’s big-wheeled. It’s big travel. It’s beautiful. And it’s Made For Fun — wherever and however you ride.


  • High modulus carbon fiber frame built around 29” wheels
  • Progressive geometry taken from the popular 2021 Alpine Trail
  • 63.5° head tube angle, 78° seat tube angle
  • 430mm chainstays, 480mm reach (size L)
  • Low-slung frame accepts long dropper seatposts
  • 160mm front, 150mm rear suspension travel

The Alpine Trail Carbon is based on the popular Alpine Trail range, replicating the progressive 2021 geometry in an all-new high modulus carbon fiber frame. It is the strongest and stiffest Alpine Trail to date. All the better for corner-smashing, jump sending, trail ripping rides. 29” wheels combined with 150mm rear travel and 160mm up front, slack 63.5° head angle, steep 78° seat angle, short 430mm chainstays and long reach (480mm on size L), plus a low-slung frame made for long dropper seatposts, make the Alpine Trail Carbon capable of pretty much anything. Leaving you to enjoy the ride.


A replaceable downtube protector helps protect the bike’s good looks from the perils of flying rocks and other trail debris. There’s also an accessory mount under the top tube to help you carry spares for those long days in the saddle.

With the Alpine Trail Carbon, all-mountain has no limits. Let your imagination take you anywhere — tough climbs, fast singletrack, complicated tech, varying gradients, bike park, or even enduro racing. The bike carries itself with grace no matter what you throw at it.

Nice simple well spec'd bike for a good price.  Great geometry, simple lines, proper tire spec* probably sold out?

*I'm assuming the website has a typo where they put the MaxxGrip on the rear and the MaxxTerra on the front... must be the other way around?

Looks accurate. For the longest time assegai only came in maxgrip in DD which is what's on the back of this build.

Marin may have been able to only secure the maxgrip DD version. Easy enough to pop that to the front and install a tannus in the back with the EXO+ casing one. That's what I would do.

Possibly, but then why wouldn’t they spec the maxxgrip exo+ on the front?  Which begs the question why they didn’t go with a DHR II on the rear... maybe supply issues?

As for Tannus... these things are the shit!  I’ve been running them front and rear paired with EXO+ casings and have been loving them. Another note... I just took them out because I sold my bike and they still look brand new!  Which wasn’t the case when I used to run CushCore... over the same amount of riding my cushcores had gashes and cuts all over them. The Tannus inserts had zero.

Thanks for the update on the older inserts you removed, Island. Now that you got me sorted with them on my hard tail, it's nothing short of amazing. I can't help thinking to myself "these things MUST be getting bagged out with all this ruckus goin on underneath me..."

How long where you running the set you removed?

If there’s money to be saved by having 1 triangle carbon, 1 triangle alloy, I’d much prefer a lighter carbon swingarm. Having a hard time seeing the value of carbon front/alloy rear frames. Gearbox and e-bikes have shown that even quite a bit of sprung mass isn’t that big of deal to the overall ride, but I know how much I hated having a boat anchor NX cassette hanging off the back.

Huh, my partners older Lapierre Spicy has that. Hadn't thought about it from the sprung / unsprung angle before.

It's harder to manufacture a carbon swingarm especially a multi-piece unit and the rear end gets smashed into rocks a lot more than the front end. I'm fine with an all metal bike, but if I was doing a mix of both I'd want the carbon up front.

Wow that’s a pretty impressive price for the spec and the contemporary geometry. Would recommend this to a friend looking to move up from a beginner bike.

Lots of geometry praise, but that's a real short CS for a big wheelbase/reach on the L/XL

Currently waiting for the XR model. Was supposed to be here on Dec 9th.
