JetBlack - JB M5 Magnetic Trainer with APP

The JetBlack M5 is a high quality, magnetic resistance indoor bicycle trainer.  Magnetic resistance allows fine tuning of your training schedule through the combination of five levels of trainer adjustment and correct gear selection.

Where a fluid trainer increases resistance according to the speed of the flywheel, a magnetic trainer can be overridden, making it suitable for recovery sessions, climbing and specifically tailored workouts.

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 Training Peaks and Strava.
