27.5-INCH MTB HARDTAIL MOUNTAIN BIKE MB.2725 SHIMANO 21-SPEED
Ride downhill on your mountain bike and speed through tight turns on varied trails – if you're an adventurous mountain biker, the new Airtracks 27.5-inch mountain bike MB.2725 is just right for you.
The 68 cm-wide handlebar and sturdy Ahead stem make handling easier on rougher terrain. Since this is a hardtail, a suspension fork is essential. Beneath the cockpit is the Suntour XCE28 with 100 mm of travel. It features sturdy steel springs that provide a linear suspension response.
The 21-speed Shimano Acera gears give you a wide gear range. For smooth, fast gear changes, they come with Shimano Acera RapidFire Plus shifters.
A must-have for every MTB – disc brakes! To ensure they provide plenty of stopping power, the MB.2725 is equipped with hydraulic disc brakes – Shimano MT-200 brakes with 160 mm rotors. Disc brakes are the right choice for frequent riders, as braking does not wear down the rim sides. This saves you from having to replace the wheels; besides the brake pads, you only need to buy new brake rotors. Another advantage becomes clear in bad weather, such as rain and mud – disc brakes work much better here than conventional rim brakes.
The 27.5" format is a comfortable size for tall and short mountain bikers and the perfect compromise between stiffness and maneuverability.
This bike is delivered 98% assembled. Only the handlebars and pedals need to be attached. Final assembly to make the bike ready to ride must be carried out by a qualified person.
