(This figure is
HyperRim type-D)
Thank you for
purchasing
Minoura's HyperRim
Trainer with RDA and our patented Hyper
Magturbo.
With its unique rim-drive system, the HyperRim is our most sophisti-
cated bicycle home trainer for both road and mountain bikes. Minoura has long
been an innovator in stationary trainers, and our new HyperRim trainer continues that tradition. The
Rim Drive Action (RDA) system has special drive pulleys that contact only the rim, avoiding wear and
tear to the tire and any unpleasant noise. With the RDA system, training is smoother, more controlable,
and quieter. Plus, you avoid the cost of replacing worn-down tires. The RDA system can handle
almost any bicycle with a wheel diameter of 26 to 28 inches and is the best trainer yet for mountain
bikes.

IMPORTANT NOTES

• Read all instructions carefully before use.
• Some assembly required.
• Keep the manual handy at all times. Lost instruction materials can be replaced
through Minoura or your local dealer.
• Do NOT use trainer for any other purpose than instructed.
• The trainer is manufactured to precise standards. You may not disassemble or
rebuild it.
• "HyperRim" and "RDA" are trademarks of Minoura and may not be copied.

Summary of Contents for MINOURA HYPERRIM

  • Page 1 Minoura has long been an innovator in stationary trainers, and our new HyperRim trainer continues that tradition. The Rim Drive Action (RDA) system has special drive pulleys that contact only the rim, avoiding wear and tear to the tire and any unpleasant noise.
  • Page 2 Remove all oils and moisture from drive pulleys before use. Keep both hands on handlebars at all times and maintain a normal riding position. After you ride bicycle on the HyperRim trainer, remove all dirt and particles from rim, so that you'll have effective braking on your future rides.

  • Page 4 The HyperRim is foldable and portable without requiring disassembly of the Mag unit and assistant roller unit. The Mag unit must be on the left side of the HyperRim’s frame, (Fig. E) and the assistant roller unit must be on the right side.
  • Page 5 Once you have set the correct position of the rim for your bicycle, you can install or Notes remove your bicycle by rotating only one hub-clamp handle. This feature saves time. The Left-side coupling has a cut-away section to accomodate the shaft of the quick- release lever.
  • Page 6 To remove your bicycle from the trainer: First, push down both white levers (see Fig. J). This releases the rollers and drive pulleys from the bicycle rim. Then rotate the hub-clamp counter-clockwise until loose, and pull out the bicycle. (Fig. J) USING THE MAG UNIT The Mag Unit has seven different levels of load force, replicating actual riding resistance.
  • Page 7 REPLACING YOUR DRIVE ROLLERS When you first start riding, the HyperRim’s rubber rollers may be stiff and cause the rim to slip. But the rollers will soften after a few rotations and will impart the proper rim grip. The rubber rollers may melt or wear from excessive heat over longtime use.
  • Page 8 (Fig. P) MAINTENANCE AND SERVICE • If strange noises or vibration persist, discontinue use immediately and return to your Minoura dealer or place of purchase for assistance.

  • Page 9 WORKOUT SAMPLE Below is a sample trainer workout for a rider who is using a mountain bike with the HyperRim trainer. This exact workout may not be suitable for everyone, but you can modify the gear ratio and load settings to suit your power and preference.
  • Page 10 This speed is not always possible on the road or trail, but you can do it on this HyperRim trainer with the lowest resistance load force and high gear ratio. We highly recommend you do not exceed 30 - 35 MPH as it will cause a problem on the bearings and/or shaft, and greatly reduce the quality of your wirkout.
