There are plenty of dirt and gravel trails that are not explored as often as they should. This season we have 2 models named Grinders to help you power through all different types of terrain.

The frame geometry is based on the BULLS Desert Falcon Pro, comfortable and made for endurance riding. The Grinder 2 comes equipped with hydraulic disc brakes, wider tire clearances, and a through axle for extra rigidity. The Grinder 1 is an aluminum frame and carbon fork, Shimano 105 groupset with Formula brakes.

The Grinders are all purpose road bikes and make the perfect companion for a commute to the office or exploring where you wouldn’t normally be able to go on a road bike. With the help of the German Marathon Champion of 2014/15, Tim Böhme worked closely with the BULLS engineers to design the GRAVEL BIKE concept.

What is behind the idea of ​​Gravel bikes?

A Gravel-Bike is the perfect "Endurance-Bike" for cyclists. Due to its versatility, there are no longer limits to where you can enjoy your ride. Get off the tarmac, from the forest path, back to the bike path. We have now built the ideal bike. It can easily be driven on all types of terrains, but it also promises a lot of comfort and is designed for longer rides.

What are the special features of the bike Grinder?

The "Grinder" from BULLS combines sportiness, comfort, stability and style. The bikes are equipped with 40mm wide tires which provide sufficient grip. The disc brakes provide security, flexible attributes add more comfort and the wheel design promises sportsmanship. The seating position has been oriented so that one is a little more upright when sitting on the bike, but still sporty enough to keep the right pace.

How was the geometry of the Gravel bikes aligned?

A Gravel-Bike is a perfect blend of a comfort oriented bike and a bike suitable for any cyclocross race. The longer wheelbase ensure superior 

stability, a constructed downtube and bottom bracket set for controlled comfort. The geometry remains sporty. We have all the advantages of both worlds united to design the perfect bike.

For whom the Gravel-Bike is intended?

The Gravel-Bike is the bike of the future. Mountain bikers and road cyclists but also tourers alike take pleasure in it and feel at “home” on this bike. It's the perfect training machine, whether a "Morning Ride" in the city or a longer endurance stroll across the country, with the gravel bike you are always prepared properly.
