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.”
