Minoura RDA 80-D Rim Drive Trainer - Blue
Sorry, this item is no longer available.
The standard tire drive system trainer must contact the tire surface and it will cause heavy noise and vibration when using a MTB's knobby tire. It's very uncomfortable for both the user and neighbors. The only one effective solution to avoid this problem is replacing the rear tire with a slick one.
A rim drive system is completely different from a standard tire drive trainer. It touches the rim side-wall where the brake shoes contact, so the roller doesn't touch the tire at all. Therefore, any type of tire can be used on RDA comfortably. In an extreme case, even a wheel WITHOUT a tire can be used on RDA. RDA is only available from Minoura.
As well as no vibration and no noise, RDA will not wear the tire at all. So you are completely free from worrying about wearing down your expensive racing tire while warming up before a race.
