Take charge of rocky mountain trails with the XDS Boss 9.1. Suntour suspension will absorb the bumps of the track and the nimble alloy frame increases handling. For greater control the Shimano Acera integrated brakes and shifters control front and rear disc brakes, and with EZ Fire Plus shift through 24 speeds of the Shimano Tourney drivetrain.


Trekking through the wilderness is a challenge. An excuse to test yourself against the last vestige of chaos in our otherwise automated world and to conquer. The XDS Boss 9.1 mountain bike lets you take command of the winding trails, steep mountains, and dense valleys of our planet, far from the roads that try to dictate us.

You’ll be putting the Boss 9.1 through the wringer, and it needs to stand up to this test. The Boss 9.1’s alloy frame is tough but lightweight, granting you improved handling and durability on unpredictable trails. However, it doesn’t hurt to have some extra insurance to support you through these wild rides, which you’ll find in the Boss 9.1’s Suntour XCT suspension forks. Additionally, the Boss 9.1 rides on a whopping 29” for improved speed and greater traction on rough surfaces.

The Boss 9.1 wants nothing more than to afford riders absolute control off roads. With Shimano Acera EZ Fire Plus shifters and integrated brake levers are at your fingertips. Shift through 24 Speeds of the Shimano Tourney Drivetrain to take charge of just about any mountain, valley, or rough trail you’ll find yourself riding through. For added safety you’ll control front and rear disc brakes for improved stopping power.

On road you follow the path laid out before you. Off road you are in charge, only limited by the strength of your resolve. Be your own authority with the XDS Boss 9.1.


Absorb Rough Bumps

Suntour XCT suspension forks absorb blows from uneven surfaces, keeping yourself and your frame comfortable. Suntour XCT also lets you adjust the travel of your suspension to tailor fit your ride.

Strong Stopping Power

Find the security you’ll need down steep trails with durable disc brakes. Disc brakes offer consistent, high performance braking power, even in wet and muddy conditions where rim brakes (caliper and V brakes) fall short.

Shimano Tourney 24 Speed Drivetrain

Shift through 3 gears with the front derailleur and 8 in the rear for a grand total of 24 speeds with this Shimano Tourney drivetrain. You’ll find the perfect gear ratio for whatever incline you come across to keep you climbing consistently.

Integrated Shifting and Braking

All the convenience of braking and shifting from the same unit with Shimano Acera Shift/Brake Levers. Shift quickly and easily with Shimano Acera EZ Fire Plus shifters to cycle through 3 front and 8 rear gears.

Lightweight Alloy Frame

With a nimble alloy frame, the boss 9.1 is lighter and much easier to handle, but still durable enough to take a knock off-road.
