Two gears. Shifted directly in the hub. Wireless. The Classified Powershift gear hub is one of the great innovations in cycling. It doubles the number of gears. This means that the same gear range is available with a single chainring as with a front derailleur. The shifting impulse is transmitted to the gearbox via a special Bluetooth axle. Everything happens discreetly inside the hub. Advantage: Clean look, maximum shifting performance and better aerodynamics. Powershift combines the advantages of 1-by and 2-by.
The BITURBO Gravel Aero Classified was developed to perfectly play off the advantages of the system. It is a stiff, comfortable and aerodynamic wheel that takes gravel biking to a new level. Whether on the race track or in daily use.
Every detail of the wheel reflects absolute perfection. The BITURBO Gravel Aero Classified is a six-spoke monocoque, manufactured by hand to the highest quality standards. The rim is 39.5 millimeters high. It has a hookless inner width of 26 millimetres, which allows the use of wide tires of up to 58 millimetres (2.3”). The rim, spokes and hub star have a perfectly matched D-shape profile. This looks elegant and guarantees optimum aerodynamics. The carbon layup was also developed for the special requirements of gravel biking. The wheel is stiff, but still offers comfort. This is made possible by good inherent damping and outstanding dynamic stiffness. With the innovative layup, we were able to achieve a wheel weight of just 578 grams.
The BITURBO Gravel Aero Classified is equipped with an original Classified hub shell. The Powershift system only needs to be inserted. It is not included. Installation at an official Classified dealer. www.classified-cycling.cc/pages/find-a-dealer
The option for the Classified Powershift system will soon be available for other BITURBO models.
