Marin Alpine Trail XR Frame Kit

The all-new Alpine Trail series is Marin's boldest and most capable line of enduro bikes ever, built upon their most advanced, most adjustable frames to date.

Series 4 aluminium MultiTrac 2 LT frames feature mixed 29”/27.5” wheels, 170mm front and 160mm rear travel, and the utmost in adjustability. Riders can alter the head tube angle and bottom bracket/chainstay length, as well as run 29” rear wheels if desired. “Bear Box” downtube storage includes a zippered nylon bag to house trail essentials, and a 34.9mm seatpost increases strength and is compatible with the latest dropper posts.

The Alpine Trail XR frame kit gives the rider the chassis to create the Alpine Trail that best meets their needs. All the essentials are included, from the rear shock to the headset, the rear axle and seattube collar. You bring your creativity and components to create the raddest bike on the trail.

MULTITRAC 2 LT

MultiTrac 2 LT debuts on the aluminium-framed Alpine Trail alloy models. MultiTrac 2 LT shifts from seatstay pivots to chainstay pivots, ensuring that the suspension performance matches Marin's design goals, which are not achievable using pivots located on the seatstay once travel exceeds 150mm. 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.

ADJUSTABLE GEOMETRY

With the integrated flip chips, adjustable headset and an aftermarket 29” rear wheel, Alpine Trail aluminium riders can select 12 unique configurations to run their bikes. These configurations allow the best fine-tuning of chassis to trail conditions available. Flip chips are easy to reconfigure trailside and easily done using a 6mm hex wrench, require no additional parts, and incorporate laser-etched graphics that indicate the position of the chips. The stock 27.5” rear wheel can be swapped out for a 29” rear wheel (not included) if desired, along with changing the position of the seatstay flip chips. Furthermore, the flip chips located at the seatstay pivots alter the bottom bracket height and chainstay length (low BB/long CS setting = 345/442mm, 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.

Bear Box Downtube Storage

The all-new Alpine Trail aluminium models now feature Marin's Bear Box integrated downtube storage, complete with a custom nylon bag with a weather-sealed zipper. The hatch door is secure and double-sealed, with bottle bosses. Keep your riding essentials safe and protected from the elements during your big ride.

ADJUSTABLE HEADTUBE ANGLE

Using Marin's proprietary headset cups and inserts, the headtube angle on Alpine Trail aluminium models can be adjusted to +0.75° or -0.75° from the standard 63° position, giving the rider three options.

PROTECTION

Chainstay and seatstays are protected with durable rubber guards that minimize noise and protect paint finishes, and integrated downtube guards helps deflect errant rocks, logs, or anything else riders may encounter on the trail.

Additionally, all aluminium frame models include a gasket around the cable exit hole reduces noise and prevents the brake hose and derailleur cable from marring the frame, and a mudflap positioned over the lower suspension pivot keeps spray and muck off the bearings. 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. They will be available as a service part for when riders make changes to their components.

ONE PIECE ROCKER LINK

The Alpine Trail Carbon utilises a stout one piece rocker link for maximum frame rigidity and suspension performance, while also allowing for bridgeless seatstays for enhanced clearance.

DOWNTUBE PROTECTION

Alpine Trail Carbon models have an integrated and replaceable downtube protector to fend off inevitable log/rock/whatever strikes that may occur when out on a rowdy ride.

CHAINSTAY PROTECTION

The chainstays on Alpine Trail Carbon models feature an aggressive chainstay protector that not only protect your frame from chain slap, but also quiet the ride.
