BIKE AHEAD COMPOSITES Wheelset 28" Biturbo Gravel AERO CLASSIFIED | Center Lock
The Biturbo Gravel Aero wheelset is now also available for the Classified Powershift gear hub. This gives you the maximum gear range with just one chainring.
The Classified Powershift system doubles the number of gears directly in the hub, replacing the conventional front derailleur and the small chainring. The shifting impulse is transmitted directly to the hub via Bluetooth using the corresponding Classified axle. The shifting process takes just 150 milliseconds and it is possible to shift under full load (max. 1000 watts).
The wheelset is based on the Biturbo Gravel AERO, but the rear wheel has been completely redesigned to integrate the Powershift system perfectly. This gives your bike an even cleaner look and features a specially developed, lightweight Classified aluminum hub body.In addition, the Biturbos from Würzburg retain their unmistakable design, with the hub star and spokes featuring a flow-optimized profile. This guarantees exceptional aerodynamics and allows you to save valuable power. Crosswind sensitivity has also been reduced. Nevertheless, the specific requirements of gravel bikers have of course not been overlooked. The layup of the carbon layers was chosen so that the high stiffness is in perfect harmony with comfort. Excellent self-damping allows the rider to sit relaxed in the saddle even after hours. Thanks to the enormous inner rim width of 26 mm, tires up to 58 mm wide can also be fitted, which additionally filters impacts away from the ground and significantly increases grip. The hookless rim flange can also withstand the odd puncture.
In terms of quality, the wheelset is definitely in the top league. All materials have been carefully selected, put through their paces and meticulously processed. The DT SWISS 180 hub installed at the front is in no way inferior and ensures smooth running and durability with its hybrid ceramic ball bearings.
The light weight of only approx. 1,250g for the complete set (without Classified Powershift gear hub) speaks for itself, but does not reflect the particularly favorable mass distribution of these wheels. Bike Ahead was able to design the construction in such a way that the rim is very light and the rotating masses are in the center of the wheel due to the lack of tensile load as with conventional spokes. This results in excellent acceleration values.
