Our indoor cycle trainers can help you both define and refine your training goals. With a combination of spin workouts and structured intervals, you can hone your ideal cadence, practice proper breathing techniques, push your anaerobic threshold and enhance overall vascular and muscular strength. These "trakstand" machines are often used to warm up and cool down at races, or before and after weight training. They can also be used as part of a cross-training program. How do they work? These products create resistance with the use of air, magnets or fluid. Of the three, the magnetic and fluid indoor cycle trainers are quieter. These units are therefore often found in apartments or shared housing situations. Air units are generally less expensive and offer the added benefit of using your power to cool you down. To use one of these machines, just hook up your bike by attaching the unit to your rear axle-an easy task. Then, get on the bike and start pedaling away. By providing pedaling resistance, the machine enables you to mimic hills and flats. What else would you expect from REI? Our Blackburn Fluid model provides easy mounting for your bike with double adjusters that center wheel on the roller. Our new, cone design fits more quick-releases. The foldable design makes this it easily portable for quick warm-ups at events.

For a realistic road feel, the fluid models increase in resistance the harder you pedal for a challenging workout! For efficient and focused workouts, the Tacx Ergo basic model comes loaded with a sophisticated computer placing a wealth of information at your fingertips. The computer records 18 different data elements relating to speed, power output, and pedaling frequency. Body weight, slope resistance (-4 to +9), and power in watts (0 to 990 watts) can be programmed to set up specific workouts. Computer functions include current speed, stopwatch, trip distance, total distance, maximum speed, average speed, current power, trip power consumption in Kcal, maximum power, and average power. Cadence functions include actual pedaling frequency, total number of revolutions per ride, maximum pedaling frequency and average pedaling frequency.
