Description

Some parts of this page are translated automatically, so please excuse any imperfections.

Rock Machine Lukk 50 is a versatile gravel bike built on a heat-treated 6061-T6 aluminum frame with fun, stable gravel geometry, suitable for a mix of asphalt, gravel roads, and light off-road terrain. The frame design emphasizes durability, comfort, and efficient power transfer.

The gravel-specific aluminum fork delivers precise handling and high stiffness while keeping maintenance demands low. FSA No.42/48 ACB headset supports front-end rigidity and stability at higher speeds.

The Shimano CUES 1×10 drivetrain with an 11–48-tooth cassette offers a 436% range, covering steep climbs as well as fast cruising on the flats. Shimano FC-U6030-1 cranks, 42T provide a balanced ratio between cadence and speed, and the Shimano CN-LG500 chain is designed for extended durability.

Braking is handled by Shimano hydraulic disc brakes with 160 mm rotors, ensuring consistent performance and good modulation in both dry and wet conditions.

Wheelset with Stars J20 rims, Shimano hubs, and WTB Nano 700×40 mm tires offers a solid balance of speed, traction, and comfort on gravel. The rear end uses a QR 9×135 mm quick-release. The bike’s overall construction is rated for a maximum load of 120 kg.

About Rock Machine

One of the established Czech companies started modestly in a garage in 1994. The latest motto is based on the basic idea - Fun First. You'll especially notice this on the trails, where Rock Machine bikes are right at home. However, other terrains - cross-country and urban - are not neglected either. The use of Shimano motors and the long-standing use of Sport Drive again offer options for everyone.
