Thank you for purchasing Minoura Magturbo Basic trainer.

This is the best cost-performance stationary indoor bicycle trainer

with completely re-designed patented magnetic resistance device

that allows you to feel real road ride feel even in your house or

garage.

This trainer fits between 24” to 27” (700c) wheels with adjusting the

If you want to ride MTB on this trainer, we strongly recommend to

replace the rear tire from knobby one to a slick one in order to avoid

vibration and noise problem caused by the tire pattern.

INSTALLING YOUR BICYCLE

Before attaching your bicycle to this trainer, turn the Hub Handle in a counter-

1

clockwise direction to open the trainer enough to easily line up your rear quick

release (QR) with the Couplings. This will make it easier to attach the rear hub

of your bicycle.

Do NOT oepn the Hub Handle too far. Otherwise the inside Nylon nut located
in the metal cap of the Hub Handle may come loose.

Loosen the Knob Bolt enough until the wheel can be placed without touching

2

the Drive Roller on Mag resistance unit. You may need to manually move the

drive roller. This is O.K. and won't hurt the mag unit.

Install the rear hub between the couplings. (see Fig. C)

3

While holding your bicycle, tighten the Hub Handle in a clockwise direction

until you see the couplings come in contact, and engage the heads of your QR

lever.

Stop tightening the handle after the couplings have engaged the Q/R.

4

You should NOT be able to move the bicycle without also moving the trainer. If

the bicycle moves within the couplings AT ALL, continue to tighten the handle

until you see no movement of the bicycle within the couplings.

Please be sure not to tighten the couplings past the point that the bicycle does

move within the couplings. Over tightening can cause both your bicycle and

trainer to sustain damage.

Be sure to check this each time you use your trainer.

Tighten the knob bolt until it starts to move the drive roller towards your tire.

It is O.K. to use your hand to assist in this process.

Once the drive roller comes in contact with your tire, tighten the knob bolt

another half or one more turn. This should provide optimal contact with your

tire.

This is a guidleine and adjustment one way or the other may be necessary in

order to provide the best contact. (see Fig. D)

Be sure too much or too few roller pressure to the tire will cause a problem
such as wearing down so quickly.

USING THE MAGTURBO UNIT

The Magturbo unit has seven different levels of load force, replicating actual riding

resistance.

The load settings range from high (H) to low (L) and can be adjusted via the white

lever on the Magturbo unit or the lever on the thumb shifter device. The rider may

also adjust the load force by shifting up or down among his 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 muscled warm up.

Increasing Load Force

To increase the load force, move the white lever on the Mag

unit toward the (H) symbol. (see Fig. E)

If your Mag unit is a remote control type, turn the lever on

your thumb shifter device toward the (H) symbol.

(see Fig. G)

Decreasing Load Force

To decrease the load force, move the white lever on Mag

unit toward the (L) symbol.(see Fig. F) 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 thumb shifter device toward the (L) symbol.

(see Fig. G)

You must not be riding the trainer when you are adjusting the white lever

!

on the Mag unit for load force. Make sure all parts have stopped spinning.
Do not try to adjust the lever with your feet while riding.

<Trouble Shooting Your Remote Shifter Unit>

If you experience your load level increasing automati-

cally, the remote shifter lever may be loose.

To solve this problem, adjust the small center knob nut

on the remote shifter device. (see Fig. H)

If you cannot shift to either the lowest (L) or the highest

(H) position, it is possible that the inner wire of the re-

mote shifter cable is too long and the wire tension is

loose. If so, please adjust the tension with the following

steps;

1.

Set the remote shifter lever at “H” position. Remove the

remote shifter device from the handlebar and straighten

the cable.

2.

Remove the plastic cap located on the bottom of the cable.

properly.
