Just Bikes JB06 GRAVEL BIKE with Shimano GRX-RX600 steel frame steel fork
Your gravel bike – a versatile and reliable companion! Ready for the next adventure tour or perfectly equipped for everyday use – the Just Bikes JB04 can handle it all. The perfect all-rounder – it transforms from a sporty racer into a comfortable touring bike or even a daily commuter. Long distances and many hours in the saddle or short trips, it's always ready to go. On-road or off-road – it rolls on any surface. Asphalt, forest and gravel paths, mud and slush – no problem. It's easy to equip for a quick sprint without luggage or with panniers on an adventure trip. There are plenty of practical bolt-on points with which you can customize your bikepacking setup.
Made of steel - strong values in terms of comfort, durability, safety and sustainability
We value and prefer CrMoly steel as a frame material due to its proven properties:
- has a high elasticity, which offers a high driving comfort, even without extra specific suspension elements
- has very good resilience, is very tough and absorbs external influences and forces more flexibly than other materials
- durable, ideal for building timeless frames
- robust and with high stability, quite insensitive to falls
- natural damping properties
- great durability, has high tensile strength and good elongation
- clean lines, slim tubes, unmistakable look with character
- durable, easy to repair and easy to recycle
