JetBlack WhisperDrive

The JetBlack WhisperDrive is a direct drive trainer with ‘whisper’ quiet and smooth magnetic resistance and is the first to be compatible with both 12x142mm 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 rock solid 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 is a direct drive trainer with magnetic resistance,
and it's the quietest trainer I've ever used.
