Whether you're familiar with the benefits of building base miles over the winter or have yet to experience the advantages in springtime form for yourself, Blackburn's Tech Mag 5 Trainer will allow you to keep your fitness up indoors over the winter without blowing your upgrade budget. With a solid, unfussy design and five resistance settings to choose from, the Tech Mag 5 is a capable addition to your winter training that won't test your limits of patience during setup. In terms of assembly, the foldable Tech Mag 5 doesn't require much. To set up your bike, the trainer comes with a quick release skewer and uses an easy to operate Fastcrank mounting system. The trainer's base is adjustable to ensure stability for different bike sizes. Not just for roadies, the Tech Mag 5 can accommodate a broad range of standard road and mountain wheel sizes from 26 x 1in to 29 x 2. 3in. For quick resistance changes from the saddle during interval sets, Blackburn includes a handlebar remote.
