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. Specifications

Get the best out of your indoor bicycle practice with the Minoura RDA80 Rim Drive Bicycle Trainer. Touted as the perfect indoor trainer for both road bikes and mountain bikes, The RDA80 improves vastly upon older bicycle trainers by using rubber rollers that contact the bicycle wheel, not the tire. This reduces tire wear, noise, and unnecessary vibration that occurs from other bicycle trainer models that rub against the bicycle tire. The RDA is perfect for cyclists who wish to practice in the off season or warm up before a race, and since the rim drive system doesn't make contact with knobby tire treads, the RDA80 is suitable even for mountain cyclists. Choose the Minoura RDA80 for a sleek and efficient practice system that won't wear you or your wheels down. This item is covered by a 5-year limited warranty.

 Smooth and Quiet, May 11, 2010

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.

Pleased with purchase., December 28, 2010
By M. Golczewski (Forest Hill, MD)

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.

 Rim Drive Trainer, January 18, 2011
By steelpolish

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...

Great product, December 14, 2011

Item performs as promised. Great alternative to purchasing new wheel for MTB. Takes a bit to get used to as it changes the feel of actually riding. I'd recommend for off season training.

Very nice. The remote is kind of silly;I use gears on bike to adjust resistance. I don't think I set it up wrong.Could have- the bike gears work just fine to mimic uphill/downhill etc. and I would recommend this product. So nice to have now that the weather is turning nasty-

Minoura RDA80R Rimdrive Trainer, October 14, 2011

This is a great product for the price. It does what it states it will do. The cable is a little long and you have to wrap it around several times, but it makes for a great work out.

Arrived very quickly, VERY easy to set up and get adjusted. Had a roller model that my son has claimed for his road bikes, decided to go with this for my mountain bikes. Vey quiet and lets me get miles in when I work late or weather makes it too bad to be outside. Not quite like being out, but is definately worth it. Made in Japan!! , high quality and not made in China. Very little noise, won't disturb others in next room, plus rimdrive allows me to keep the knobbies on. Noticed that this years Tour de France winner Evans starred on mountain bikes first.

Very quiet unit with plus advantages, if that is what you need., September 18, 2011
By The_Professer (South Florida)

At first after reading the flaming reviews I registered to return the unopened item. After talking with another biking associate I decided to try it first and I am glad I did.
This unit is ultra quiet. All you hear is a slight swishing sound from the magnetic resistance unit. I am not a sprinter or heavy power user so the available resistance settings are more that adequate for my use.
Easy to setup if you read and follow the simple assembly and setup instructions.

Well worth the price!, August 30, 2011
By S. Bernal (Durham, NC United States)

I just got my trainer last night and it was relatively easy to setup. It is very sturdy and made of quality parts. I looked at other trainers but I was sold on this one by the fact that you don't have to change your back tire to a slick one if you have a mountain bike. It's not too heavy and it folds nicely so you can store it when not in use. Made in Japan(Not China!) and Minoura has an office in CA that will support this product!
