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 sophisticated 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.

WARNING
Use two-wheeled bicycles only. Tandems may be used if balanced correctly.
!
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.
Please obey warning signs.
Check the couplings supporting the rear hub for damage
!
and cracks. Accidents may occur from cracked or damaged
couplings.
When using the HyperRim trainer, place it on a flat surface for safe training.
!
Adjust the drive-pulley height so they are even and touching the bicycle rim only (not
!
the tire).
Do not over tighten the hub-clamp handles. Over-tightening may cause damage to
!
the trainer or bicycle frame. The clamp handles should be a snug and secure fit. Do
not force!
Keep away from small children.
!
Before use, make sure all bolts and nuts are securely fastened.
!
X
When installing your bicycle, make sure the rim is located in the center of the frame.
!
This centering can be achieved by rotating the hub-clamp handles.
Keep hands and feet away from spinning rollers and wheels at all times.

Prior to assembly of the Mag Unit, locate the two
2
bolts and two washers. Find the left-side slot on the
trainer. While placing the Mag Unit at the recommended position on the inside of the slot, attach it
with the bolts and washers by using the included hex
wrench.
(see Fig. B)
After installing the Mag Unit, put the Height Adjust
Knob (this is optional) through the hole on the left
side slot, and then tighten it to the thread on the Mag
Unit’s support base. This optional Height Adjust
Knob will help you adjust the height of the Mag Unit
so that the rubber roller will fit properly on the rims
side wall. (see Fig.C)

Mag unit must be assembled on the left side
!
of HyperRimTrainer and the Assistant Roller
Unit on the right. Follow directions EXACTLY. See diagram for accurate placement. After deciding the height of the
pulleys tighten handle securely to avoid
damage to equipment and/or rider.
(see Fig. D)
Handle with care! Damage may occur if Mag unit is dropped.
!
Install the Assistant Roller unit to the right side of the frame, using
3
the same process as with the left-side Mag unit. Make sure the
assembly is secure and accurate. (see Fig. E)
Notes
The HyperRim is foldable and portable without requiring
disassembly of the Mag unit and assistant roller unit.
(Fig. D)
The Mag unit must be on the left side of the HyperRim’s frame,
!
and the assistant roller unit must be on the right side.
Both drive pulleys must be adjusted so as not to touch the tire.
You do not need to set this adjustment at this stage of the assembly --- you can adjust it later, before use. Once you have set the
height of the pulleys, you must tighten the bolts firmly. If they are
loose, the assembly may break and/or damage your bicycle.
INSTALLING YOUR BICYCLE
Before installing your bicycle, rotate both hub-clamp handles counter-clockwise to create a wide
1
clearance between the couplings. (see Fig. F)
Place the bicycle's rear hub between the two
2
couplings, making sure that the quick-release
skewer (or hub nut) is not yet touching either
couplings. Then rotate the hub-clamp handles
clockwise to fix the rear hub. Tighten until securely
fastened, but do not overtighten.
