With winter in full fear many cyclists are likely stuck on trainers. But LeMond is now offering an optional wireless power meter attachment for its LeMond Revolution stationary trainers. This add-on, which will retail for around $250, will help cyclists monitor their power a little more closely.
The WattBox, which can connect to a smartphone app and bike computer via ANT+, can calculate wattage based on the trainer’s wind resistance unit, and take into account air temperature, humidity and altitude. This can in turn provide an accurate reading based on the amount of air moved by the resistance unit’s fan.
“Now anyone with a LeMond Revolution trainer can effectively gauge their output,” said company founder Greg LeMond. “Research in cycling performance always brings us back to the most critical reading, which is wattage,” LeMond said. “Knowing this number and working with it opens the door to knowledge and improved riding. By creating the WattBox, we are putting the processor in the WattBox unit, which allows any software update in the future or a small hardware change.”
We were saddened at last year’s Interbike Trade Show to learn that LeMond Fitness had closed shop. But now comes word that the company’s revolutionary stationary bike trainer is back in gear so to speak. Greg LeMond announced a new company called Lemond Inc, which will retain rights to the Revolution Trainer. Moreover, Lemond (the company) will introduce a number of Revolution compatible accessores designed by LeMond (the person) and his team. 
Wahoo Fitness has put a new spin on cycle training with its KICKR Bike Trainer, which can be controlled via an iPhone app. This looks a bit like the Lemond Revolution Trainer, which works much like a traditional cycle trainer but instead of spinning on a drum has users ditch the rear wheel completely by offering a cassette and gears. Resistance is controlled via the app, which also lets riders know the speed and watts produced. It reportedly can simulate different conditions such as riding uphill, where more effort is required.
