A reliable gravel bike equipped with Shimano GRX 10-speed

The Megamo Jakar 30 raw 2027 is an aluminum gravel bike designed for riding on asphalt, dirt roads, and gravel tracks. Its triple-butted AL 6061 gravel frame uses hydroformed tubes and internal cable routing, while its carbon fork contributes to comfort on uneven surfaces.

This version features a 20-speed Shimano GRX RX-400 drivetrain with a 46-30 tooth double chainring and an 11-36 tooth Shimano HG50 cassette. This setup offers a wide range of gears to adapt pedaling to flat sections, long distances, and changes in gradient.

The Jakar 30 also features Shimano RX-400 Flat Mount hydraulic disc brakes, Megamo Gravel GR 700 tubeless-ready wheels, and WTB Riddler 700x45 tires with tan sidewalls. Its Megamo gravel cockpit is paired with a Satori New Viper stem, the length of which varies depending on the frame size.

Frame
