INDUSTRY REVIEWS

“Quality-spec brakes and drivetrain for price; good-looking; equipped with a dropper post” - BikeRadar

ONE-PIECE LINK

Sometimes simple is better! The linkage-actuated single pivot offers active and progressive suspension making for a supple ride on technical sections and a playful ride on flow trails, while the one-piece pivot bridge reduces flex and saves weight.

SUNTOUR SUSPENSION

The Suntour XCM Boost fork and Raidon LO shock offer 120mm of travel, with adjustable rebound and lockout on the fork and air pressure and lockout adjustment on the shock to dial in the perfect ride for your weight and riding style.

SHIMANO DEORE 1X10 DRIVETRAIN

The Shimano Deore 1x10 drivetrain offers a wide 11-42T cassette range and crisp, reliable shifting, ensuring you always have the right gear for any situation. The Shadow Plus derailleur enhances chain retention for a quieter and more secure ride.

DROPPER POST

The TranzX Dropper Post offers versatile travel options with 150mm for smaller frames and 170mm for larger frames, allowing riders to quickly lower their saddle for improved maneuverability and control on descents.

SHIMANO HYDRAULIC DISC BRAKES

Shimano MT200 hydraulic disc brakes provide powerful and consistent stopping power, giving you confidence and control on descents and technical trails.

The bike is great. My first full suspension bike and meets all my needs and skill level. Love the color and process went smoothly using Bikesonline. My only dislike, which isn't really that big of a deal, is that the tires aren't tubeless ready.
