- Potholes, fire roads … this favorite aluminum model says, “Bring it on.”

We’re proud of all our aluminum Haanjo models for their capabilities as road bikes with mountain bike attitude. The Diamondback Haanjo 4, however, ups the ante considerably. We took our aluminum frame and added thru-axles front and rear to give it even more precise handling. Next, we added a carbon fork, which pushes the mute button on rough chip-and-seal roads and washboard sections of trail. The component package includes TRP Spyre C Flat Mount Mechanical Disc brakes and drivetrain components for performance, weight savings, and durability.

HED Tomcat Disc wheels and grippy WTB Riddler 700x37c tires roll smoothly on pavement but can take plenty of abuse off-road. Potholes, fire roads, wherever you choose to go … the Haanjo 4 says, “Bring it on.”

- 6061-T6 aluminum alloy frame with Endurance Geometry for worry-free durability and all-day riding comfort. Rear thru-axle reduces lateral frame flex

- DB Gravel Performance full-monocoque carbon fork with 12mm thru axle smooths road chatter

- Shimano GRX400, 10 speed, gives you a gear for any terrain

- Powerful TRP Spyre mechanical disc brakes and fatter tires makes this a truly capable bike

- HED Tomcat Disc wheelset is quick and takes a pounding
