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.
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.
LEARN MOREONE 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.
SUSPENSION SETUP
REAR SHOCK SET UP
Recommended Sag = 30%/19.5mm
Step 1: Set correct pressure in rear shock.
Step 2: Sit on the bike and cycle the suspension (*with correct riding gear).
Step 3: Reset O-ring and sit on the bike, DO NOT BOUNCE, carefully step off.
Step 4: Measure sag (from o-ring to seal of shock), If it does not match the bike’s recommended sag in millimeters repeat process.
Step 5: Adjust rebound setting to ensure proper control.

Comparable to Higher-End Chairs, Solid Build and Support Without the Premium Price
Color: Black Full Mesh, Style: Executive, Color: Black Full Mesh, Style: Executive
I’ve been using this chair for a bit now and it’s been a genuinely upgrade. The build quality stands out right away, it has real heft and doesn’t feel cheap or hollow. Everything fits together cleanly and once assembled it feels stable and planted. I’m over 6 ft and 200+ lbs and it handles that without any issue, no creaking or sense that it’s being pushed to its limits.
There’s enough space in the seat and back that you don’t feel boxed in. I added an extra ergonomic cushion and it still feels roomy, which isn’t always the case with chairs in this category. The adjustability helps a lot here, especially the lumbar support. Being able to move it up and down and also forward and back makes it easy to actually get it where you need it, instead of just accepting a fixed position. The armrests are also easy to dial in, especially if you’re switching between typing, reading, or leaning back a bit. The tilt range is useful, and the tilt tension is stronger than I expected. Even at my size it takes a bit of effort to lean back, which I see as a positive since it feels controlled and supportive rather than loose or overly easy to recline. The mesh is another strong point. It came in perfect condition, no snags, no loose threads, no rough edges anywhere. There weren’t any bits of untrimmed plastic on the frame either, which says a lot about the quality control. The mesh itself is taut with a bit of bounce, so it doesn’t sag but still has some give, which makes long sitting sessions more comfortable.
Assembly was straightforward and clearly thought through. The instructions are easy to follow, but what stood out were the built in redundancies that keep you from second guessing anything. There are multiple left and right indicators when installing the arms, a clear front facing marker for the gas lift, and the screws are labeled in the packaging so you’re not guessing which goes where. It’s one of the smoother assembly experiences I’ve had.
I also reached out to activate my warranty and had a very positive experience. I spoke with Alice who was very knowledgeable, quick, warm, and they went out of their way to help me with whatever I needed. When I inquired about the extra screw holes under the chair, she let me know that this was for a foot rest which was still in the production phase and unprompted offered to have one shipped to me when they were ready! There is an excellent team behind the product.
Overall: well built chair with good materials, thoughtful design choices, and good adjustability to make it work for different setups. It feels durable, comfortable over longer periods, and especially well suited if you need something that can handle a larger frame without sacrificing support.

Excellent chair/great support.
Color: Black Full Mesh, Style: Executive
Excellent, comfortable chair! I was surprised at how easy it was to assemble---but the directions were super clear and all the pieces and parts were labeled. Once I received the chair, I was also surprised with the email follow up from Alice at Molents. All this for a reasonably priced chair.

Great Ergonomic Support and Fit, with Minor Adjustment Caveats
Color: Black Full Mesh, Style: Executive, Color: Black Full Mesh, Style: Executive
As someone who is 5'4" and 140 lbs, the size of the chair feels ideal, and the seat cushion is spacious without feeling overwhelmingly large. The breathable mesh material is high quality, keeping me cool during long working sessions while still feeling sturdy. The back support and adjustable lumbar feature aligns perfectly with my spine and has noticeably reduced my posture fatigue. The height adjustment mechanism operates smoothly to align perfectly with my desk, and the assembly process was surprisingly straightforward, taking less than 20 minutes with clear instructions and tools included. My only slight hesitations are regarding armrests not being long enough. The wheels are not easy to roll on carpet and require a bit of extra effort to move. Maybe a chair mat might be helpful on carpeted floors. However, for the price, the comfort and build are impressive.

High quality and incredible customer service
Color: Black Full Mesh, Style: Executive
This is an extremely well made chair at a very competitive price. The packaging, assembly instructions, as well as the way the hardware was packaged and labeled is probably the best I've seen. I'm particular about tools, and the included allen wrench was better than the normal "included tools" so much so that i actually used it rather than one of my own. The assembly was easy, and the chair itself looks and feels very high quality, and is very comfortable. Perhaps best of all was the level of customer service. I emailed on a weekend to activate the warranty and request the free cushion they offer. I got a personal response in less than a day and they offered upgraded wheels for free as well. This is a company worth doing business with.

Great product AND customer service!
Color: Black Full Mesh, Style: Executive
I'm having a hard time writing this review because I can't tell which one I like better: the product or the customer service!
I work on a computer all day, so a comfortable office chair is critical for me. This chair is great - it's adjustable in every way I need it to be, especially the armrests. The breathable mesh is both durable and supportive, and is more comfortable to sit in than the "overstuffed" chair it replaced.
Let me just say: no company provides better customer service than MOLENTS. Right after assembling my chair (which was very easy, btw), I registered for the 2 year warranty they offer. The NEXT DAY I received an email from Alice in their customer service department 1) to confirm my warranty, 2) to tell me about the free foam seat cover they were sending me, and 3) to make sure the chair was comfortable and easy to assemble. Very few companies take the effort to follow up with customers right after making a purchase like that.
I'm extremely happy with this purchase. This chair is worth MORE than it's weight in gold, and I strongly recommend to anyone thinking about buying an office chair to buy it from MOLENTS - you won't regret it.
Oh, and if Alice's supervisors are reading this: she absolutely deserves a promotion!
