You should NOT tighten the wheel axle by tightening the left side knob.
This is for pre-adjusting the wheel position to the exactly center of the drive roller only.
Securley tightening your bike to the trainer should be done with the right side hub handle only.
WARNINGS
Use two-wheeled bicycles only. Tandems may be used if balanced correctly.
Keep both hands on handlebars at all times and maintain a normal riding position.
Check the couplings supporting the rear hub for damage and cracks. Accidents may occur
from cracked or damaged couplings.
When using the trainer, place it on a at and horizontal surface for safe training.
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 t. Do not force!
Keep away from small children, and keep hands and feet away from spinning rollers and
wheels at all times.
Before use, make sure all bolts and nuts are securely fastened.
• Read all instructions carefully before use. And Keep the manual handy at all times.
• Do NOT use trainer for any other purpose than instructed.
• The trainer is manufactured to precise standards. Disassembling without Minoura’s ap-
proval may void your warranty.
• Minoura offers 1-year limited warranty on the Mag unit and 5-year on the frame.
For more detail, refer the enclosed “Minoura Limited Warranty Policy” card.
IMPORTANT NOTES
You may use the quick release skewer currently on your bicycle, however we recommend
replacing your quick release skewer with the supplied one and keep installing the coupling
protector cap on to the right side coupling of the trainer.
Otherwise the stability will not be guaranteed.
Open the legs fully to get maximum stability.
Remove the coupling protector cap when you use a hub nut type wheel.
We don’t recommend to continue using your own quick release skewer for your safety.
Wipe all oil and moistures out from the rim surface and rollers everytime you use the trainer to
keep necessary brake performance of your bicycle.

HOW TO SETUP YOUR RDA80 TRAINER
Bike Direction
Insert the left side of the skewer (Q/R lever side) into the left side
coupling, and adjust the rotation of the coupling so the skewer lever
sits securely in the large cut-out (see Fig. E).
This will prevent damage to the skewer during use.
(Fig. A)
Fully open the legs and place RDA80 on a at and horizontal oor.
Conrm all 4 leg points are touching the oor at same time to ensure the maximum stability.
NOTE: If the both legs don’t touch the oor at same time and if one side leg has been
slightly lifted up, pull up another leg upward strongly then place the trainer on the
oor again.
Open both couplings by turning the Left Side Knob (see Fig. B) and the Right Side Hub Handle (see
Fig. C) anti-clockwise.

(Fig. B) (Fig. C)
Left Side Knob Right Side Hub Handle
Install the Mag Resistance Unit on the left side slot
and the Assistant Roller on the right side slot beside
the trainer pillar by the supplied M6x12 bolts.
(see Fig. A)
NOTE: We recommend you to use the
reinforcement plate (SR-13) for installing
the Mag unit. This plate will sandwich
the slot plate from outside for mounting
the heavy Mag unit and giving it extra
stability.
Required Tools: M5 hex wrench
(Fig. D)

NOTE: Do not over-loosen the couplings, otherwise the knob
or the hub handle may become unthreaded inside the
frame.
NOTE: We suggest not using the left side coupling for major ad-
justment. Moving it too much to one side will cause mis-
alignment. The left side coupling is used only to provide
easy intitial adjustment for your hub length. (see Fig. D)
(Fig. E)

Hold the bike rmly by hand and turn the right side hub handle clockwise until the coupling comes
into contact with the right side skewer nut.

(Fig. F)
Adjust each height of the Mag unit and the assistant
roller to t to your rear wheel perfectly and tighten
the bolts rmly. (see Fig. F)
(Fig. G)
7Adjust the wheel position by checking the double-
circle position indicators on both side.
The best position should be each indicator can be
seen equally, but if your rim is narrow, you should
adjust the wheel position to be a little left (toward
Mag side) to prevent unexpected slippage problem.
NOTE: Note that the left side knob is NOT for
tightening the axle. It is only for pre-
positioning the wheel. Clamping wheel
securely must be done by the right side
Hub Handle.
THE SKEWER NUT PROTECTOR
We strongly recommend you to use the supplied skewer at all times if
your rear wheel is a quick release skewer system. This will guarantee a
t with our couplings and remove any chance of misalignment. (Fig. H)
The right side coupling has a black plastic Skewer Nut Protector (called a “Grommet”). This is to protect
the skewer nut from damage during use.
If your rear wheel is not designed for the quick release skewer and uses a hub nut system, you should re-
move it by inserting a rod or a pen to the hole (see Fig. H) and then lifting up the Grommet.
NOTE: We will NOT guarantee any tting problem or accident caused by using your own skewer
on the trainer.
NOTE: When you use the supplied skewer, you should keep the Grommet on the coupling.
Hole
Each rubber roller is made to contact
the rim ONLY. Contact with the tire may
cause the tire to burst during use.

The Mag unit has 7 different levels of load force, replicating actual riding resistance.
The load settings range from high (H) to low (L) can be adjusted via the side lever on the Magturbo unit or the
lever on the remote shifter lever. You may also adjust the load force by shifting up or down among your gears,
depending on the level desired.
We recommend that you start with a medium to low load force and gradually work up, increasing force as your
muscles warm up.
Increasing Load Force
Decreasing Load Force
To decrease the load force, move the side lever on Mag unit toward the (L)
symbol. (see Fig. M)
Be sure the lowest selection is not zero load, there still be a small level of force.
If your Mag unit is a remote control type, turn the lever on your re,pte shifter
toward the (L) symbol. (see Fig. K)
To increase the load force, move the side lever on the Mag unit toward the (H)
symbol. (see Fig. L)
If your Mag unit is a remote control type, turn the lever on your remote shifter
toward the (H) symbol. (see Fig. K)
(Fig. M)
HOW TO INSTALL THE REMOTE SHIFTER

1) Wind the band around the handlebar and hook the metal ring to the gutter on the remote shifter base,
then 2) ip up the lever to lock (see Fig. I). If it is loosened, adjust the band tighter.
The soft fabric band is pre-adjusted to t normal 22mm diameter handlebar.
If you need to mount onto an oversized or specially shaped handlebar or stem, adjust the band (see Fig. J).
At this moment, you should slide the guide pin downward to loosen the band for easier work.

The R model has a convenient remote shifter lever. You can install it on the handlebar or stem, then you can
control the resistance level without getting off the bike.

To make any adjustment to the unit, make sure you are off
the bike, and that the trainer has come to a complete stop
and that nothing is still moving.
If you cannot shift to either the lowest (L) or the highest (H) position, the in-
ner wire of the remote shifter cable gets extended and the wire tension becomes
loose. Please adjust the tension with the following steps;
(Fig. O)
TROUBLE SHOOTING YOUR REMOTE SHIFTER UNIT

Set the remote shifter lever at “H” position. Remove the remote shifter
device from the handlebar and straighten the cable.
Remove the plastic Cap located on the bottom of the cable. (see Fig. O)
Hold the adjusting screw with your right hand and push it towards the di-
rection of the outer cable, then adjust the nut with your left hand to make
the wire tension properly.
ABOUT SLIPPAGE PROBLEM
The pateneted roller system used in the rim drive models from Minoura is made to t a wide variety of bi-
cycles and wheels. Therefore, you should expect that sometimes the rollers will slip a little on your rims. This
is completely normal and due to the spring mechanism we use that provides a t with such a large variety of
bicycles and wheels.
If you experience slippage all the time you use the trainer, check the belt tension rst by pushing down the belt
with your nger. The K-16 V-belt will be worn down after long term of use but most reason for the slippage
problem is caused by improper (too much or too less) tension adjustment.
To adjust the belt tension, loosen both upper and lower bolts which hold the pulley arm by an M5 hex wrench,
then pull the arm outward by your hand and tighten the bolts rmly again.
If the V-belt is completely worn down or damaged, replace it.
This work requieres high skill for disassembling and assembling the Mag unit. If you don’t have condence,
please ask to the Minoura dealer where you purchased the trainer.
The instructions manual will come with the replacement V-belt kit, also you can download it from our web site
(http://www.minoura.jp).
