The Kinetic Magnetic series of trainers is one of the most popular out there, and for a few simple reasons: it's durable, it's simple to use, and it's very fairly priced. The latest generation, the Kinetic Magnetic 3. 0 Trainer, makes a few incremental improvements to continue its reign. Many things are still the same, though, and we think that's just fine. The stable aluminum chassis still feels like you could throw it off a building although this may or may not fall within Kinetic's unconditional lifetime warranty. As always, the trainer comes out of the box fully assembled, and it folds flat for easy storage. New this year, however, is the trainer's nine position thumb lever which allows you to adjust the trainer's resistance. The Mag trainer's progressive resistance is linear, up to 850 watts at 40 mph. Overall, the resistant increments are calibrated to offer greater resistance in the middle of the range from 1 32mph, compared to most fluid trainers, making the Mag 3. 0 great for lower geared machines like mountain bikes or cyclocross rigs. The resistance mechanism is also highly efficient at dissipating heat, making it more consistent than many competitors, and it's also extremely quiet, so it's easy for you or your spouse to live with. The Kinetic Magnetic 3. 0 Trainer comes in the color Green only, and with a handlebar mounted, cable actuating remote for the resistance mechanism. The trainer can accommodate 22 to 29 inch 700c wheels, and the box includes the necessary cone cups and Kinetic skewer for mounting your bike in the chassis.
