When the weather's not cooperating, a bicycle trainer is the perfect training tool for staying in shape. Work on your cadence, strengthen muscles, tone, and build a perfect fitness regimen with an indoor trainer. A bike trainer or set of rollers can be the perfect tool for warming up before a race. We carry fluid and magnetic trainers, hybrid trainers that employ both means of resistance, as well as tire-drive, rim-drive and wind trainers. For building balance, a set of rollers and a good deal of shear determination will get you on the right track. Rollers help you work on bike handling, learning to hold a straight line and build endurance. Riding your bike on rollers also gives you an incredible workout. You need to keep spinning to stay on.
