The JetBlack M5 Pro is a high quality, magnetic resistance bicycle trainer. The magnetic resistance allows fine tuning of your training schedule through the combination of five levels of resistance 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. The JetBlack M5 Pro features a handlebar mounted remote lever for resistance adjustment, and comes equipped with a HYDROGEL Roller, which reduces noise by 55%, and tyre wear by 25-30%, giving you the ultimate quiet and smooth ride.
