Alpine Trail E Bosch je naše největší a nejvýkonnější rodina kol. Posouvá možnosti o krok dál oproti modelům Alpine Trail E. Nové eMTB Alpine Trail E Bosch jsou postaveny na zcela nových rámech Series 4 z hliníku MultiTrac 2 LT, které přinášejí významná vylepšení pro jezdce, kteří se nebojí těch nejnáročnějších a technicky nejtěžších terénů, stejně jako pro ty, kteří vyžadují maximální dojezd.

Zvýšili jsme zdvih o 10 mm na obou stranách, nyní je 170 mm vpředu a 160 mm vzadu, a přemístili klouby na řetězové vzpěry, aby odpružení splnilo požadavky na výkon a nastavitelnost u delšího zdvihu. Jezdci mohou upravit úhel hlavové trubky o +/- 0,75° přesunutím spodního pouzdra hlavového složení, zatímco výšku středu a délku zadní vidlice lze změnit pomocí flip čipů na sedlové vzpěře.

Pohonné jednotky Bosch Performance Line CX dodávají točivý moment 85 Nm a jsou podporovány velkokapacitními 750Wh bateriemi PowerTube, které jsou bezpečně umístěné v rámové spodní trubce. To vám dává největší baterii v nabídce Marin pro ty největší dobrodružství.

Model Alpine Trail E2 (Bosch) nabízí prémiové odpružení Fox a 12rychlostní pohon Shimano XT spolu s naší vlastní CNC 35mm představcem a kombinací Trail Bar.

Technology

SERIES 4 ALUMINUM FRAME

Alpine Trail E models are built upon our 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, compatible with modern coil or air shocks.

MULTITRAC SUSPENSION

Marin developed the all-new Series 4 aluminum frame in conjunction with the new human-powered Alpine Trail models and notable new features shared between the platforms. Firstly, travel has been increased by 10mm at both ends, now standing at 170mm (f) and 160mm (r), which is also an increase of 10mm beyond the current Shimano-equipped models. MultiTrac 2 LT (“Long Travel,” 150mm+), with rear pivots relocated from the seatstays to chainstays, makes its eMTB debut and delivers the suspension performance and tunability demanded of the longer travel. With MultiTrac 2 LT, the benefits of relocating the rear pivot points from the seatstay to the chainstay become apparent, as it reduces anti-rise, allowing for better chassis control while braking, more mid-stroke support, and better feel at bottom out. Furthermore, relocation of the pivots provides the added benefit of allowing for adjustable chainstay lengths and bottom bracket heights. Ultimately, it’s a better-riding, better-performing suspension system made possible by the new pivot placement.

The Shimano-equipped Alpine Trail E features the same great, proven MultiTrac suspension technology, but optimized for the Shimano STEPS system. With this combination there is no need for platform or lockout levers, just get on and blast up the hills. 160mm front/150mm rear travel.

ADJUSTABLE GEOMETRY

Adjustable geometry features are new to the Alpine Trail E Bosch models—integrated chainstay flip chips and an adjustable headset yield six possible configurations to suit a variety of trails best.

Flip chips are easy to reconfigure trailside and are quickly changed using a 6mm hex wrench. They require no additional parts and incorporate laser-etched graphics that indicate the position of the chips. Furthermore, the flip chips located at the seatstay pivots alter the bottom bracket height and chainstay length (low BB/long CS setting = 347/443mm, high BB/short CS setting = 352/435mm) so that riders can perfectly dial their bike in to match the terrain they are looking to conquer.

Finally, using our proprietary headset cups and inserts, the headtube angle can be adjusted to +0.75° or -0.75° from the standard 63° position, giving the rider three options to best suit their preferences.

MIXED WHEEL SIZES

29” front and 27.5”+ rear wheel sizes are the ideal combination for the Alpine Trail E, with larger front wheel easily rolling over most any trail obstacle and offering the best cornering traction, while the burly 27.5” rear setup adds playfulness and enhances acceleration and braking traction.

PROTECTION

Shimano models: A stout and durable rubber guard protects the chainstay, while a durable and replaceable guard on the leading edge of the drive unit keeps the internals safe from whatever the rider is likely to kick up on the trail. CushCore inserts enhance tire performance and traction while also protecting the rims on the Alpine Trail E2 and E1 models.

Bosch models: Chainstays and seatstays are protected with durable rubber guards that minimize noise and protect paint finishes. Made from a 30% fiberglass-infused nylon, similar to what is used on safety and football helmets, the moto-inspired integrated downtube guard helps deflect errant rocks, logs, or anything else riders may encounter on the trail. This guard also includes drain ports to let moisture flow from the frame. Cable ports are of an all-new design and keep the frame innards sealed. These ports use rubber membranes punctured during initial assembly and seal around the housing or hose once inserted. Out at the wheels, CushCore inserts enhance tire performance and traction while also protecting the rims on both models.

DROPPER POST OPTIMIZED

The modern day trail rider needs their saddle out of the way at times, while low-slung frames require longer length posts. On the Alpine Trail E, seat tube lengths have been minimized, along with minimum insertion depths, so that riders of all sizes can get the proper extension needed.

Suspension Setup

REAR SHOCK SETUP

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.

FORK SETUP

Marin recommends that all bikes front and rear suspension feel balanced

Step 1: After rear sag is set follow the recommended pressure from the fork manufacturer.

Step 2: Bounce evenly up and down on the bike, cycling the suspension up and down to make sure both front and rear suspension feel balanced, if the front does not match the rear add or release pressure.

Step 3: Once the bike feels balanced adjust the rebound damping to ensure proper control.
