Orbea Laufey Onna 50 29 2024 terracotta red/green mountain bike (R20621NA)

Frame and Construction

Orbea Laufey Onna 50 29 2024 features a solid and lightweight aluminum frame, ensuring durability and lightness of the construction. The Orbea Onna Alloy frame is designed with internal cable routing, which not only improves the bike's aesthetics but also protects the cables from damage in tough terrain conditions. The use of 9x135 dropouts and BSA BB standard ensures compatibility with a wide range of components.

Controls and Suspension

The bike is equipped with a 720 mm wide aluminum handlebar and a stem with a 7º angle, providing precise handling and a comfortable riding position. The front suspension is based on the SR Suntour XCE 28 fork with 100 mm travel, which effectively absorbs terrain irregularities, allowing confident obstacle negotiation. Integrated 1"-1/8 Semi-Integrated headset guarantees smooth and stable steering.

Drive System and Gearing

The Orbea Laufey Onna 50 29 2024 drivetrain is based on a 2x8 configuration, giving the user 16 gears to choose from. Shimano M315 and Tourney TX800 derailleurs along with Microshift TS38 shifters provide precise and reliable gear changes. The forged aluminum crankset with 22x36T chainrings ensures efficient power transfer, while the Sun Race CSM66 cassette with an 11-34T range offers a wide gear spread.

Braking System and Wheels

Shimano MT200 hydraulic disc brakes offer excellent braking performance regardless of weather conditions, enhancing user safety. The 29-inch wheels, built on Mach1 ER20 19C rims, and Kenda K1153 2.35" tires provide excellent grip and stability in various terrain conditions while offering riding comfort.

Advantages

Front cushioning
The cushioning on the bike provides comfort when negotiating bumps in the road. This model features front wheel cushioning, which absorbs the force when hitting an obstacle and increases the level of safety.
Aluminium frame
The aluminium frame is characterised by its high resistance to scratches and damage. In addition, this material is characterised by its low weight, which makes carrying the bike no problem.
Hydraulic disc brakes
This mountain bike is equipped with hydraulic disc brakes, which have a very low failure rate so that use will be trouble-free, even during frequent use. In addition, they feature greater braking power and modulation.
29" wheels
The use of 29 wheels has made it possible to provide more and better tyre contact with the ground, which makes it much easier to overcome bumps when riding over rough terrain. This size guarantees good stability when riding at higher speeds.
