Diamondback Hook Cross-Country 27.5" Adult Bike
If you were to choose just one bike – only one – the Diamondback Hook would be the ideal selection. It's a bike that's ready for practically any adventure you dare to undertake. Whether it's a speedy dash through your local trails, enduring day-long journeys that take you deep into uncharted territory, or any riding scenario in between.
The Hook shares the same sleek, modern frame as its upscale Line and Sync'r counterparts. With a longer front end, a shorter rear, and a low, agile profile, the Hook is remarkably nimble and precise on narrow trails while providing unwavering stability when you're pushing the limits on steep descents.
However, what truly sets the Hook apart is its affordability. Diamondback ensures that your wallet remains intact by outfitting the Hook with outstanding yet budget-friendly components. These include a plush 120mm fork, a straightforward and efficient single-ring drivetrain, powerful disc brakes, and quick-rolling 27.5" wheels.
