Frequently asked questions about the Bombtrack Hook
Is the Bombtrack Hook suitable for bikepacking?
Yes, especially for light bikepacking or weekend adventure riding on mixed routes. It has a balanced geometry, many useful mounts and very predictable handling when the load remains moderate.
Is it better suited to asphalt or dirt?
The Hook is designed to perform well in both contexts, but it shines on asphalt, white roads and fast-rolling dirt. It is a versatile gravel bike, not a platform designed for technical off-road or heavy structural loads.
What is the difference compared to the Hook EXT?
The standard Hook is more oriented toward speed, rolling efficiency and mixed everyday use. The Hook EXT, by contrast, is more focused on technical dirt riding, larger tire clearance and more aggressive adventure setups.
Is the Shimano GRX 2x10 drivetrain a good choice for an all-round gravel bike?
Yes. GRX 2x10 offers a very balanced gear range for riders alternating between asphalt, climbs, light dirt and long rides. It is a particularly coherent solution for a versatile gravel bike like the Hook.
Why does the Hook use different wheel sizes depending on frame size?
To preserve consistent geometry and balanced handling across all sizes. XS and S use 650B, while M to XL switch to 700C: a smart choice to maintain handling, comfort and proportions.
Can it also be used every day?
Yes. The Hook also works very well as a one-bike solution for sport commuting, training, long rides and mixed routes. That is one of its strongest qualities.
Is it suitable for light touring?
Yes, as long as the load remains light to moderate. For short trips, micro-adventures and use with light bags it is very convincing. If you expect substantial continuous load, however, a more touring-oriented platform remains the better option.
Summary
The Hook is a balanced and versatile gravel bike, designed for riders looking for a platform that moves naturally between asphalt, white roads and fast-rolling dirt. The Columbus Cromor steel frame, Shimano GRX 2×10 drivetrain and size-specific geometry make it a convincing platform for endurance riding, sport commuting, light touring and advanced everyday use.

Bike size recommendations are intended as a useful general guideline to quickly narrow down the options based on rider height. Bike fitting is a complex topic and also requires considering other measurements and factors. Since no two human bodies are perfectly identical, it is not possible to provide a recommendation that is 100% accurate for everyone. As a result, Bombtrack cannot guarantee that the stated recommendations are correct for every individual customer. The best way to determine the correct size is to contact your Bombtrack dealer (info@bikejamming.it) or a professional bike fitter, who can identify the most suitable size.
