The Marin Alpine Trail, which was released during our
Pond Beaver coverage in September, has now been made in carbon.
The frame is a literal carbon copy of its aluminium counterpart with the same 150mm rear travel matched with a 160mm fork, and the same MultiTrac, four-bar suspension system. The geometry is identical too with a 63.5° headtube angle, 78° seat tube angle, a 480mm reach in size L and the same aluminum 430mm chainstays.
Alpine Trail Details • Wheel size: 29"
• Carbon front triangle, aluminium rear triangle
• Travel: 150mm rear / 160mm fork
• 63.5° head angle
• 430mm chainstays
• Sizes: S-XL
• Price: $3,189 - $4,099 USD

marinbikes.com Marin claims the change to carbon makes this the strongest and stiffest Alpine Trail to date and there's also a claimed weight saving of 1.5kg over the Alpine Trail XR in size Large.
GeometryBuildsThere are two carbon builds available at this time and a frame only option. The Alpine Trail Carbon 1 comes with a RockShox Yari RC fork Deluxe Select+ shock. The drivetrain is Shimano Deore 12 speed with FSA Comet crankset and Shimano also provides the MT420 4-piston brakes. Maxxis Assegai 29 x 2.5” tires sit on Marin rims with Shimano hubs. Price: $3,189 USD / $4,199CAD / £3,045 / €3,659.
Moving up a price bracket, Alpine Trail Carbon 2 instead gets suspension from Fox with a 38 Performance fork and DPX2 shock. You also move up the Shimano range and get a mix of SLX and XT drivetrain components, an FSA GRadient crankset and SLX level brakes. Price: $4,099USD / $5,499CAD / £3,995 / €4,699.
The Alpine Trail Carbon models will be available in early 2021, more info,

hats off to
hats off (to someone)
A phrase used to express congratulations to someone. (The removal of one's hat is typically a gesture of respect.)
Hats off to you for getting the big promotion!
A: "I managed to get the highest number of sales this quarter!" B: "Wow, hats off! That's not easy to do!"
The Bird Aether 9C is full carbon, but in a Large frame size actually weighs the same as a GG.(2840g without shock).
I don't think Fezzari's in a similar format (130-160mm) are any lighter despite their full-carbon construction.
So Marin has a done a real good job of shedding a decent amount of weight (3.3lbs) from their alloy model without sacrificing the durability of the rear end.
People have such strange ideas about durability. I just as often hear someone recommending carbon for greater durability as aluminum for the same reason, even on the same component.
Still, good price on a good frame no matter what it's made of IMO.
Exactly. If the weight, features, performance, durability, and price check out, it doesn't matter what it's made from.
Also, I am sure anyone on an SB150 would argue that it is definitely an enduro bike.
The review here specifies a Fox Performance 38, the Marin site specifies a Fox 38 Performance Elite. Can one of you confirm with @MarinBikes? If it is in fact a Performance Elite and the bike is still $5k CDN thats an awesome deal! I blew up an image of the damper dial but couldnt make it out Thanks!!
It seems to be working just fine on the new wreckoning, but the new meta got some criticism for it.
Brands that have been pushing this long and slack numbers for a while, like geometron and pole, spec their bikes with massively longer chainstays.
Did you find the Optic to little suspension? That is a bike I really appreciate, largely because it is so similar to the Rift Zone which I thoroughly enjoyed (my RZ Carbon 2 is getting put back into stock mode soon to sell)
What is the weight of this new bike?
However I’d rather be on a 29 so I’m selling the MV9 and getting the ATc 2 as soon as available
Still don’t understand how Marin manages to make beautiful bikes like this one , and some serious ugly other ones
Modern Geo: Check
Reasonably priced: Check
Need more bikes like this with this type of thinking. Getting guys into the game at a reasonable price and although I'm just as much as a fan of the best and lightest and newest and coolest, this thing is attainable and looks to be extremely capable.
I think this bike is still relatively cheaper in the US, but it's a lot closer than it would seem because of tax and price reporting differences.
The former would be a fairly decent price, while the latter isn't as attractive in comparison to bikes like the new Canyon Spectral 29 IMO...
Truly for the people.
Hidden bike secrets yet again.

In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where it is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the linkage. However, the linkage must also know where it was.
The wheel guidance linkage scenario works as follows. Because a variation has modified some of the information the linkage has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
There are only 2 variables that control wheel path in a single-pivot: main pivot location and swing arm length. There are 8 in a four-bar: each pivot location and the length of each bar\arm.
If you want to get real picky, they should have called this a single-pivot bell-crank (1st class lever) driven design, since a single-pivot with a 2nd or 3rd class lever (think Canyon Spectral or Cannondale Jekyll) changes the leverage in a different way because of how those linkages move their own pivots.
Yes, maybe it's just semantics, but details are important in engineering, and talking about suspension design fits that bill.
Never been true.
Four-bar has _always_ referred to how the axle/hub is located, regardless of the how the shock is actually driven.
This thread is not about which is better or worse, just trying to be clear, because knowledge is power. I actually like (and have owned and ridden, along with a DW-link) both single-pivot with falling anti-squat that starts just under 100% around sag, and horst-link with a lower but more consistent anti-squat. Both give awesome traction that I like. but there are small things for each that are also preferential: a single pivot is often intuitively predictable as far as where the wheel will be, and the horst can (but doesn't have to) maintain that anti-squat through most of the travel along with very minimal chain growth. Both are good, and yet the feel of both can be modified drastically via the system that drives the shock.
