Indoor cycle training isn't just for roadies anymore. With the Minoura RDA80R rim-drive trainer, mountain bike and BMX owners can get in on the fun, too.

The trainer's dual rollers squeeze the tire's rim, preventing wear and vibration.

Ideal for riders who want to practice in the offseason or warm up before a race, the trainer drives the rear wheel by contacting rubber rollers to the rim's sidewall. Because the trainer doesn't touch the tire at all, there's no wear, noise, or vibration caused by the tire tread pattern--a terrific feature for bikes with knobby tires.

The trainer works by pinching the rear wheel rim with rubber rollers from both the left and right side. The V-belt drives the trainer's resistance unit on the left side, while the right side roller supports the rim from the opposite side to avoid damaging the wheel. Each rubber roller is pushed toward the rim by the spring, so even if you pedal strong and the wheel position is moved sideward, both rollers with automatically chase the rim. As a result, the rim stays healthy, as the material on the rubber roller is almost the same as the material on a standard brake shoe.

The RDA80R is well built, with a stylish Ergo-type frame that includes a pair of brackets on each main pillar. The trainer's mag resistance unit, meanwhile, coordinates with the machined-steel 1.75-pound flywheel to create seven levels of resistance, all controllable via the remote control shifter (included) on your bike's handlebar or stem. The RDA80R works with a range of tire sizes, from 20 to 26 inches, although the ideal size is 21 inches or larger due to the bent bracket design.
