TRP and Classified present the Vistar // Powershift groupset, an innovative shifting solution for gravel and road bikes. The system combines a 12-speed cassette with the Classified Powershift hub. This effectively creates 15 or 16 individual gears, which, according to the manufacturer, represents the widest range of all current gravel and road bike groupsets. A 1x15 configuration is available for gravel bikes, while road bikes can be equipped with 1x16 gears. At the heart of the system is the Classified Powershift hub, which integrates a highly efficient 2-speed drivetrain in the rear hub instead of a front derailleur.
Intelligent shifting with QuantumShift technology
A special feature of the Vistar // Powershift system is the so-called QuantumShift technology. This coordinates the shifting of the Powershift hub with the shifting process on the rear derailleur to ensure a logical gear sequence. In contrast to conventional 1x or 2x drivetrains, this should also be possible under full pedalling load. Riders can choose between the automated QuantumShift mode and manual shifting, in which all 24 gear combinations can be controlled individually. The wireless CMD "Command" system from TRP ensures reliable communication between the shift levers, rear derailleur, Powershift hub and accessories.
Focus on ergonomics and braking power
The developers have placed particular emphasis on ergonomics when designing the shift levers. According to TRP, one finger should be sufficient for braking, regardless of hand size. This should improve safety and control for all riders. The RD-G8000E rear derailleur is characterised by a lightweight but robust design and promises precise, low-noise shifting performance. The rear derailleur battery is removable and rechargeable, which should make maintenance easier.
Versatile compatibility and chainring options
To ensure broad compatibility, TRP and Classified offer various chainring options. For road bikes, 50- and 52-tooth variants are available, while gravel bikes can be equipped with chainrings from 44 to 48 teeth. Classified also offers an aerodynamically optimised crankset with chainrings from 46 to 52 teeth. The cassettes from TRP are made of steel and designed as a monobloc version, which should ensure optimum integration with the Classified Powershift hub.
Practical testing of the new gearshift unit
The reliability of the Vistar // Powershift system has already been tested under demanding conditions. The shifting group has been used in elite gravel races such as the Unbound race. Classified athlete Arno Van den Broeck used the system during his 200-mile race in Kansas, which proved the performance and robustness of the groupset.
The new Vistar // Powershift groupset is available now and costs €2,800.
