    Blasting around the mountains has never been so much fun. The Marin B-17 2 full sus trail bike is made to get the most out of your riding, featuring 27.5+ MTB wheels with big tyres for more grip and float on rough terrain.

    Marin’s Series 4 6061 aluminium frame is lightweight and features MultiTrac suspension for smooth riding on 27.5+ wheels. The RockShox Deluxe RT shock controls the 120mm travel to take on rough trails. Boost spacing is found front and rear, with 15x110mm front and 12x148mm rear spacing. This helps add stiffness to the frame and fork, while also allowing for space for the tyres and keeping the chainstays short. Internal cable routing and 29” wheel compatibility finish off this trail bike frame.

    The RockShox Revelation RC has the same chassis as the Pike, delivering the same steering accuracy and control with 130mm travel.

    Shimano gives movement to the B-17 2, with their 1x11 speed SLX drivetrain. Smooth shifts and reliability are all a part of the game, while a wide 11-42t cassette offers a range to tackle any mountain. Shimano MT500 disc brakes make sure speed is always under control, and allowing for great modulation and power in any weather scenario.

    The wide 2.8” Vee Tyre Crown Gem tyres allow for a greater amount of float on the trails, helping out the suspension travel to create a softer and more controllable ride. A TranzX Dropper post helps to get the seat out the way on the fun stuff going down.

    Get ready from plus sized mountain bike adventures with the Marin B-17 2.

    The B-17 combines our acclaimed 120mm MultiTrac rear suspension system with 27.5+ tires for an all-day, all-conditions trail bike ready for the unknown. The large volume tires allow for extra low tire pressure and unheard of grip and control in most every condition for an instant confidence boost at speed, and uncanny climbing abilities to conquer the next ridge. At nearly the same outside diameter as 29” tires, 27.5+ tires offer similar roll over capabilities, but with added float and an even larger tire to ground contact patch to help tame the trail.

    The B-17 is our most capable MultiTrac bike, built for the all-day trail rider looking for a playful bike with maximum traction. Plus-sized tires are an instant confidence boost and traction upgrade, sticking to most everything and making it possible to climb and descend sketchy parts of trail that may have required hoofing it before.

    Highlights:

    SERIES 3 ALUMINIUM FRAME

    The B-17 has a Series 3 6061 butted and hydroformed aluminium frame with 120mm travel MultiTrac suspension technology and large volume 27.5+ wheels.

    27.5+ WHEELS

    27.5+ tires roll fast, grip anything, and their wide high volume low pressure setup brings a new experience to trail riding. The B-17 is compatible with 29” wheels up to 2.5” for two rides in one frame.

    MULTITRAC SUSPENSION TECHNOLOGY

    MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedalling platform. The rocker link provides a progressive leverage ratio for the rear shock for small bump sensitivity and the feeling of a long travel system on large drops and rocks.

    INTERNAL ROUTING

    B-17 models come equipped with internally routed dropper posts, with internal rear derailleur routing for a clean look and snag free ride.

    148X12MM THRU-AXLE

    Boost front spacing is paired with a 148x12mm Boost rear thru-axle for frame and wheel strength, and future wheel upgrade compatibility.
