The JetBlack WhisperDrive TM is a direct drive trainer with ‘whisper’ quiet and smooth magnetic resistance and is the first to be compatible with both 12x143mm and QR135mm/QR130mm axle systems. The direct to drivetrain interface gives you the benefit of zero tyre wear and easy setup. No more winding in of caps or lugs. The JetBlack  trainer has a rocksolid design with the front legs positioned closer to your centre of body mass than any other direct drive trainer. Now you can give it everything during a sprint session or interval training with efforts upward of 1,200 watts.


The JetBlack WhisperDrive TM eliminates variations in resistance from tyre contact or air pressure, meaning you can repeat exactly any trainer session and monitor your training progress. When used with the full range of JetBlack sensors, you can enjoy training sessions identical to those used by professional cycling teams. You can even upload your session to Strava!


The JetBlack WhisperDrive TM, like all JetBlack trainers, comes with a lifetime warranty.


Includes both sensors for Virtual Power App support (speed & cadence sensors). Power calculated in JetBlack app and third party apps.
