28" men's trekking bike TR.2825 trekking bike 24-speed Shimano Alivio RD-M3100 SGS Shadow
Functional trekking bike for everyday use & leisure
The Airtracks TR.2825 focuses on the essentials: reliable technology, comfortable handling, and practical everyday equipment. This 28-inch men's trekking bike is ideal for daily rides, leisure, and longer tours.
Shimano Alivio 24-speed gear system
The Shimano Alivio RD-M3100 SGS Shadow 24-speed gear system ensures precise and reliable gear changes. This allows comfortable riding on flat roads, in the city, and on slightly hilly terrain.
AXA lighting with hub dynamo
Instead of classic battery lights, the TR.2825 features a powerful AXA lighting system with Shimano Nexus hub dynamo. This ensures reliable lighting on every ride – without battery changes.
Low-maintenance V-brakes
The installed V-brakes impress with easy maintenance and reliable braking performance in everyday use. They provide safe control in both dry and wet conditions.
Everyday practical equipment
SKS mudguards reliably protect against rain and dirt. The pre-installed Racktime ECO 2.0 luggage rack allows easy attachment of panniers or bike baskets, making the trekking bike especially practical for everyday use.
Eco-friendly Schwalbe tires
The Schwalbe Road Cruiser tires offer good grip, comfortable riding, and reliable puncture protection. The tread is partly made from renewable and recycled materials.
Subtle & modern design
The simple gray design looks modern and unobtrusive at the same time. This makes the bike ideal for daily use in the city and on tours.
