27.5-Inch Men’s MTB Mountain Bike RTX 1×12-Speed SRAM SX Eagle, Suntour XCM34 Boost
The RTX is a high-quality 27.5-inch mountain bike specifically designed for demanding off-road adventures. It is equipped with a 1×12-speed drivetrain featuring SRAM SX Eagle components, delivering precise and reliable gear selection even in challenging terrain. The robust aluminum frame ensures high stability and durability while maintaining a low overall weight. The Suntour XCM34 Boost LO DS suspension fork with a 15QLC thru-axle provides excellent damping and control, keeping you confident and secure on rough trails.
TEKTRO M530 hydraulic disc brakes deliver powerful and precise braking performance in all conditions. The bike is fitted with Schwalbe Nobby Nic Performance tires (70-584) in black, offering outstanding grip and durability across a wide range of terrain—from hard-packed gravel paths to muddy trails. The 27.5-inch wheels strike the perfect balance between speed and control. The 1×12-speed SRAM SX Eagle drivetrain provides a wide gear range, ideal for tackling steep climbs as well as fast descents.
The RTX offers the perfect combination of stability, precision, and performance to confidently master any off-road challenge. With its high-quality components, it is a first-class companion for all mountain bike enthusiasts.
This bicycle is delivered 92% pre-assembled. The final road-ready assembly of the handlebar, front wheel, and pedals must be carried out by a qualified professional.
