The Boost Trainer Bundle offers all of the benefits of the Boost Trainer, with the bonus of Garmin's Speed Sensor assisting with your workouts. It's the optimal choice for power training and data tracking. The Boost Trainer benefits from a closed resistance unit for a quiet ride, and the trainer's magnetic brake offers an opportunity for power-based workouts and high-intensity interval sessions. The trainer also features a flywheel for a road ride feel. Front-wheel stability comes from the same support system that turns the trainer into a portable carrying system.
