General information about our shipping
Great product, works well with my Garmin GPS AND great service getting it to me so quickly Merlin Cycles.
Sync'do with the Garmin 510 immediately and a three year old can fix it onto the revolution. Instant power reading. Very happy. Just wish it was standard and cheaper!
The Watt Box Power and Speed sensor equipped with Lemond Revolution Trainer is the best bike training tool I have ever used. Perfect compatibility with Wahoo Fitness Apps on my iPhone 5s.
Need the Watt box to have meaningful experience on the trainer. Works well.
Enables you to train indoors in a structured way, easy to "pair" with your Garmin. Highly recommended to buy at a great price from Merlin Cycles.
