An ELITE Real Axiom trainer realistically simulates outdoor riding & means that you can train indoors on those rainy, snowy or windy days or when it is too dark to ride safely. You can use it during the long & cold winter months or throughout the year to prepare for important races & to evaluate & improve your training & athletic performance. The home trainer adjusts resistance automatically based on rider speed & the course selected. The computer screen displays a video synchronized to the bicycle's speed, & shows important training data such as speed, power, heart rate, pedal cadence, slope & elapsed time.
