Classified & TRP 2025 2026: Vistar Wireless 1x15 Gravel and 1x16 Road Groupsets Now Available
Introduction to the Vistar Powershift Drivetrain
The Vistar Powershift wireless electronic drivetrain system, co-developed by TRP and Classified, is now commercially available. This innovative system enables 1x (single-chainring) drivetrain configurations with an effective 15 speeds for gravel setups and 16 speeds for road configurations. The technology integrates a 12-speed TRP cassette, managed by a wireless electronic Vistar rear derailleur, with Classified's 2-speed Powershift internal gear hub. This combination delivers a 1x setup that provides a gear range comparable to traditional 2x systems.
Functional Features of the System
Externally, the TRP + Classified Vistar Powershift system appears as a conventional 1x12 dropbar drivetrain. However, the 2-speed planetary gear reduction integrated within the rear hub effectively generates 15 or 16 unique gear combinations. TRP's wireless electronic dropbar shifters offer two operational modes:
Manual Sequential Shifting: Allows for sequential gear selection across all 24 total combinations (essentially a virtual 2x12 drivetrain), similar to operating a front derailleur.
Intelligent QuantumShift Function: This mode automates gear management, providing 15 or 16 "intelligently sequenced gears." The system automatically coordinates internal hub gear changes with rear derailleur shifts to ensure logical transitions and smooth cadence steps across the entire gear shifting range, overcoming the discontinuities typical of conventional 2x drivetrains.
Technical Specifications
The Vistar Powershift system is offered in two primary configurations:
Virtual 1x15-speed gravel groupset:
1x chainrings ranging from 44-48 teeth.
11-36 and 11-40 tooth cassettes, providing up to a 520% gear range.
Virtual 1x16-speed road groupset:
1x chainrings of 50 or 52 teeth.
11-30, 11-32, and 11-34 tooth cassettes, providing up to a 450% gear range.
Further technical details include:
Cassettes: CNC-machined steel monoblock construction, specific to the Powershift rear hub.
Powershift Hub: Enables instant 2-speed shifting (1:1 to 1:0.686 gear ratio) even under full load.
Communication: TRP CMD wireless ANT+ & Bluetooth LE protocol for seamless control of the Powershift hub and other paired accessories.
Power Supply:
TRP Vistar wireless rear derailleur: Removable rechargeable battery with proprietary USB-C charger (rated for 10,000 shifts).
Bar-end control unit: Two replaceable LR44 batteries (non-rechargeable), wired to TRP Vistar shifters.
Powershift Smart thru-axle controller: Micro-USB rechargeable battery.
All batteries feature a "deep-sleep" mode for bike transport.
Braking: Trusted mineral oil TRP hydraulic disc braking system.
Crankset: Carbon TRP Vistar crankset, available in 165, 170, 172.5, and 175mm crankarm lengths.
