BLACKBIRD 27.5 2021

BLACKBIRD 27.5 2021

Description

Enduro demands maximum versatility from a bike – difficult and long uphilling, downhilling in the most difficult conditions, jumps and drops are the standard challenges that the equipment must face.

Based on our own and our riders’ experience we placed a stiff single-pivot construction at the bike’s heart. This simple solution makes it possible to create a modern bike that fulfills the demands of even the most demanding riders. The advanced swingarm cage, consisting of 12 welded elements and tubes, is very stiff and the carefully designed pivot position allows high pedaling efficiency (with the antisquad parameter at about 100% pedal-bob effect is eliminated). The swingarm is connected to the front triangle with a super stiff 17mm axle, mounted on three Max type bearings packed with waterproof Mobil grease. The design of the shock mount yoke means a full length seat tube can be used, enabling plenty of room for the new long travel dropper posts. The frame design is based on modern, progressive geometry suitable for 27.5" wheels with a low positioned BB, a relatively long front triangle and a 65° head tube angle. The Blackbird climbs with ease but it will really come alive when shredding down. 

New version of Blackbird 27.5 frame for the 2021 season is designed for the 230x65mm metric shocks and 148x12mm Boost hubs.

Available options: w/o shock; w/RS Super Deluxe Select DebonAir.
