The brand new Marin Alpine Trail is a 29er enduro and trail bike, and becomes their most aggressive mountain bicycle for 2019. It gets 150mm rear wheel travel with 160mm forks, a high-end alloy frame and long, low geometry. It’s implied to go fast, get rowdy, take a whipping, and after that get you back to the top of the mountain for the next stage.
The concept behind this, and all of their mtb, is to produce something that’s enjoyable to ride, is spec ‘d for durability, and be simple to own. As such, it’s a budget-friendly single pivot style, depending on a linkage driven shock to control the kinematics and mindful part selection to put the performance where it delivers the most significant bang for the buck.
The brand-new Alpine Trail utilizes their Series 4 alloy frame, where their Hawk Hill, Rift Zone and B17 use Series 3. The differences are that Series 4 frames have more advanced tube shaping, more complex forgings for things like the bottom bracket and shock yoke lower section, a formed and created rocker link, and complete internal routing.
It’s constructed on their MultiTrac suspension platform, like a few of their other designs, however is built for more aggressive riding. That suggests a larger main pivot and rocker link pivot, with larger bearings, and larger bearings at the rear pivot, too. This helps it handle the longer 150mm travel, that makes more movement at each pivot, and creates a stiffer frame.
They kept the rear pivot above the rear axle to offer it better pedaling performance than if they ‘d opted for a four-bar linkage by putting the rear pivot on the chainstay (prior to the axle).
The rocker link is one piece, taking two forged halves and welding them together with upper and lower shelves to produce a quasi-box section. This makes it really stiff, which let them remove a seatstay bridge and keep the needed frame tightness. It’s developed around a metric trunnion mount shock, which utilizes a broad installing bracket for much better stiffness and less torsional impact. So, it should all remain moving easily regardless of how hard you’re whipping through the surface.
The air shocks are tuned for a more linear stroke, utilizing one of the smallest air volume spacer setups, suggesting you can update to a coil shock without affecting bottom out avoidance. Stock alternatives are a Fox or X-Fusion O2 professional R, the latter getting bigger positive and negative air volumes than previously, together with a brand-new transfer port to better balance air pressures.
The primary pivot huges and utilizes an expanding collet design to lock itself into location and avoid play.
The bike is created around huge 29 × 2.6 tires, and yes, it’s intended just as a 29er … not a 27.5+ bike. They say an appropriate 27.5 ″ version might follow, or a carbon variation. Or both. But for the future, you’ll be able to select from 2 build specifications on this alloy frame:
The Alpine Trail 7 has Shimano M7000 shifter with SLX derailleur, e13 9-46 11-speed cassette, Tektro Orion brakes, Vee Tire Circulation Snap Tackee 29 × 2.3 tires, and house wheels and alloy cockpit with X-Fusion Manic dropper post. Fork is the Rockshox Yari RC, shock is X-Fusion O2 Pro RXC. MSRP is $2,650 (EUR2,700 BARREL included).
The Alpine Trail 8 gets SRAM NX Eagle rear shifter & & derailleur, with the lighter GX cassette, Tektro Slate T4 brakes, and KS LEV dropper post. Figure about 30lb for a complete bike with tubes in it. Fork is a Fox 36 Performance with a Float DPX2 shock out back. MSRP is $3,600 (EUR3,800 VAT consisted of).
Both are offered late summertime. Across the line, their multi-linkage Attack Trail line is gone, now it’s just this MultiTrac platform and
the React2Play system designed by Darrell Voss. Alpine Ridge First Trip Review
I had a day to shred the brand-new Marin Alpine Ridge at the Les Gets bike park in France, and it satisfied. Mainly, I used the lifts and ripped down the mountain, preferring the natural tracks over the bermed bike park lines. With a lot of roots and rocks and technical descents, I had ample opportunity to evaluate the suspension. It carried out on par with other 150mm bikes I’ve ridden, tracking through the terrain in a well regulated way. Which should not come as a surprise thinking about Marin’s EWS background with their other frames … they have a strong structure of understanding to build on. Considering the price point, which is about half of many bikes I end up evaluating, it is quite a pleasant surprise. Simply goes to show how far down awesomeness has dripped over the past couple of years.
I just did a little climbing, generally to backtrack for repeat picture runs, so I can’t speak with its far away climbing up performance. But I did attempt couple of steep, twisting singletrack areas both seated and climbing (a couple times each), and it appeared to work well even with the shock fully open. Standing did generate some bobbing, however seated climbing felt far more effective. My hunch is, with the shock locked out (or just set to company), it ‘d be a capable climber able to obtain you back to the top without using you out. Another good surprise was the Vee Flow Snap. My test bike had it only on the front (these were pre-production and ended up needing to pull what they could to get them constructed in time for this launch), however it handled the wet roots, muddy sections and loose scrabble quite well.
The essential thing for a bike like this to get right is the suspension and frame efficiency. And with tires costing what they cost nowadays, beginning with a good set of those is a good plus, too. With this solid structure, it becomes a platform worth updating, and Marin seems to have been successful on that front. Several other journalists appeared equally pleased with its ride quality, and a couple of key upgrades might quickly make the bike more lively as the budget plan allows.
