TRAINER FOR ALL SEASONS. Stick to your fitness plan year round with the help of the CycleOps Mag+ trainer. It is the perfect way to keep your legs warm when it's cold, dry when it's wet, and safe when it's too dark to ride outside.
Simply attach the handlebar-mounted shifter to change resistance during your workout without having to leave your bike. Want to train with Zwift or CycleOps VirtualTraining? All you need is a speed sensor.
