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.

Going from road riding to using this thing took a little getting used to, but after about 20 miles I had no problems. The setup was very easy and I can ride with my two small children asleep in the next room.

I bought this to hook up to my old mountain bike to use this winter to get in shape. Very easy to set up and quality of frame is excellent. I bought the version with the remote cable tension adjustment. Probably not needed as switching gears will likely change the tension enough. It's incredibly quiet as the only point of contact is the braking area on the back tire.

The trainer will lift the back tire about two (2) inches from the floor. I used a few 2x4's to prop up the front tire rather than buy a front tire brace.

I've also gotten into the habit of releasing the tension springs on the two friction wheels that contact with the back tire when I don't use it. I don't want there to be any flat spots on the tension wheels themselves. Might be a bit overboard but would rather be safe than sorry.

I have a bunch of burley mountain bikes that never see a slick tire, ever. This trainer allows me to run my gnarley bikes without any issues. I have used it with my trail bike, a dirt jump single speed, and a full on downhill race bike. The bikes easly and quickly mount up to the trainer, and the rim drive friction unit clicks up against the rim with a snap of a lever. The rim drive unit uses soft rubber drive wheels that roll along the rim, so it wont rub the paint off of the rim if you use disk brakes. The unit is very well built and sturdy. Operation is very smooth and positive. I got the remote option which I would recommend due to its ease of use. You wont be sorry with this fine piece of Japanese engineering...
