Important Notes

• For use with a normal 2-wheel bicycle only. Do not use a tandem, recumbent, track racer or
other.

• The right side coupling has a black plastic cover (Grommet) in standard on LR340. This is for
protecting the quick release skewer's nut from scratching, but if you use a bike with the nut
type rear wheel axle, remove Grommet for better stability.

• Fits tire size between 24" and 700x45c (ETRTO 47-622). To use 24x1.75" or smaller tire, install
the supplied Small Wheel Adaptor between the Mag unit and the base bracket. 29" tires may
not be used on LR340.

• Some assembly required. Use correct tools (10mm spanner and M5 & M4 hex wrenches).
The kit contains only M5 hex wrench.

• Use the supplied rear quick release skewer for maximum stability. The hub clamping parts
(couplings) ts the supplied quick release skewer only. Minoura is not responsible for any
problem caused from using your own skewer.

Please read carefully before use

• Use on at and level oor or ground for your safety.

• Adjust the roller pressure to the rear tire properly in order to maximize your tire life.

Tire and roller contact will eventually wear both your tire and the trainer roller.
Wipe the tire surface to remove any solid dust away before setting the bike on the trainer in
order to maximize the drive roller life.

• Check and adjust the remote shifter cable tension properly when you cannot set at L or H even

though you turn the shifter lever.

• Touching the spinning wheel and/or any other moving parts while training may cause serious
injury. Keep children and pets away from the trainer when in use.

• It is not possible to convert the remote controllable resistance unit to the non-remote version

one. Removing the remote shifting device means xing the resistance level at the highest
range.

• If you feel any strange noise or smell, stop using LR340 immediately and contact the retailer

where you purchased the trainer.

• To protect the oor or carpet from stain and sweat during workout, we recommend you to put

a sheet or mat under the trainer and bike.

• Any warranty will be void if you use LR340 for other purpose than instructed.
Minorua offers 1-year limited warranty on this product from the date of your purchase for any
problem caused by manufacturer's defect.
Any damage or problem caused by transporting process is not covered under warranty. Any
damage from shipping or moving must be made to the shipping company.

How To Setup Your LR340 Trainer

Required Tools: 1 x 10mm Spanner & 1 x M4 Hex Wrench

Replace your rear wheel quick release skewer to the supplied one.

1.

Minoura guarantees the stability only when using the supplied skewer due to the coupling inner
shape.

!

!

Install the Mag unit and the Roller Pressure Adjust Knob set (MF-3) to the frame.

2.

Once remove the pre-installed pivot bolt and nut
from the Main Frame (see Fig. A).
Attach Mag unit to the bracket on frame, align the
holes, and put through the pivot bolt.
Tighten the pivot bolt with 10mm spanner and M5
hex wrench. (see Fig. B-1)

If your bike is not equipped with quick release skewer and it's a hub nut type, you
should remove the black plastic Grommet (Skewer Nut Protector) (F-9) from the
right side Coupling (F-1).
Minoura doesn't guarantee the stability if you don't remove the Grommet.

You don't need the supplied quick release skewer if your wheel is a hub nut type.
It's not possible to convert your wheel from the hub nut type to the quick release
skewer type unless replacing the hub.

Put the acorn spring and the flat washer to
the knob bolt.
Attach the Wing Nut from behind the
bracket on the frame, then screw the knob
bolt into the T-nut through the hole.
(see Fig. B-2)

!

If you have overtightened the
pivot bolt, the Mag unit will not
move smoothly even if you
rotate the knob bolt.
The proper installtion is that
the Mag unit will come down
slowly with its own weight
when you loosen the knob bolt.

Make sure the acorn shaped spring

direction and the at washer position

are as shown in Fig. B-2.

Failure will cause difculty on rotating.

flat and level floor. (see Fig. C)
At this moment, make sure all 4 foot are
contacting the floor at once to sit on the
floor stable.

At this point, turn the Hub Handle two more rotations. Do not try to over-tighten the Hub

!

Both right and left side couplings are
designed to suit the supplied quick release

skewer. The left side coupling must t

perfectly in the skewer head to get correct
stability. (see Fig. E)

Any skewer type which lever is located on
the end of the axle (like Fig. F) or the lever
will not be bent over right angle (like Fig. G)
cannot be used on LR340.

Do not try to over-tighten the Hub Handle
to keep the correct thightness of rear hub
clamping.
Too tight of a setting will cause damage to
both the LR340 and your bike frame.
Too loose of a setting may cause the bike
to come out of the trainer during use.

Contact the Drive Roller to the rear tire by turning the Roller Pressure Adjust Knob clockwise.

(see Fig. H)

The best position is that the roller compresses the tire in the depth of 3 – 4 mm. (see Fig. I)

Please note: Too little or too much tire pressure will cause premature tire wear.

!

Always check the contact between your tire and the trainer roller and keep your

tires correctly inated.

TIPS

The rear tire should sit just off center of the drive

roller without touching any other part of the Mag
unit. (see Fig. J)
If the tire touches the plastic parts (see Fig. L)
for any reason like the rear wheel is not trued
correctly or you have installed a wide tire, you
must adjust the Mag unit position.

If it's hard to tighten the knob bolt due to the Mag unit weight, lift up the Mag unit by
hand then tighten the knob.

(Fig. H)

(Fig. I)

There are two sets of installation thread holes
on the bracket. Choose either one for better
positioning.
Also, you can micro-adjust the position. To do so,
loosen the backside screws with M4 hex wrench,
adjust the roller position side to side, then tighten
the screws again tightly. (see Fig. K)

!

To remove the bike from the LR340, loosen the micro adjust knob first, then loosen the Hub Handle.

7.

If you remove the bike without changing the roller position, the next installation may become
difficult because the rear wheel has been pushed forward by the roller.

If the rear tire has touched any other parts than the Drive Roller, that part may be
damaged and your tire will wear out quickly.

How To Install Remote Shifter

Required Tool: 1 x M4 Hex Wrench

LR340 comes with a convenient remote shifter device.
By installing it on your handlebar or stem, you can adjust the
resistance in 7 different levels without getting off the bike.
The remote shifter should be used in conjunction with the
gears on your bike to achieve maximum efficiency in your
workout.

How to install the remote shifter

1) Wrap the flexible plastic band around the handlebar,

2) Put the hook to the gutter on the plastic shifter base,

3) Flip up the lever to lock.

The remote shifter is pre-adjusted to fit the standard handlebar size;
22mm (7/8") diameter.
If it becomes loose or too tight, or you need to install the shifter onto
an oversized handlebar or stem, adjust the band length by turning
the plastic screw on the band with an M4 hex wrench.
(see Fig. O)

(Please be advised that the hex wrench doesn't come in the package)

The plastic band and screw are not made to be abused.
Do not over-tighten.
You should take off the hook before adjusting.

How To Adjust Resistance Level

How to increase the resistance level

Twist the shifter lever toward "H" symbol

How to reduce the resistance level

Twist the shifter lever toward "L" symbol

!

"L" is not zero resistance. There is still some resistance
at "L" level due to the roller compression to the tire.

Why My Remote Shifter Doesn't Work Properly?

If you have a shifting issue where you can't set the remote at L or H, your cable may be stretched.
To fix this problem, follow the adjust the cable tension.

Set your remote shifter at "H" position and remove the shifter from your handlebar, then straighten

1.

the cable as much as possible.

Pull out the plastic cover cap on foot of the remote cable. (see Fig. Q)

2.

Hold the inside adjusting screw and push it toward the shifter, then adjust the locking nut to set the

cable tension properly. (see Fig. R)

Install the cover cap again.

How To Use Small Wheel Adapter

Required Tools: 1 x 10mm Spanner, 1 x M4 Hex Wrench

If you wish to use a tire size 24x1.75" or smaller,
you need to install the Z-shaped "Small Wheel
Adapter" between the Base Plate and the Mag
unit to raise up the roller height. (see Fig. S)

The direction of Z-adapter is fixed so follow
the arrow printed on the top and make sure it's
pointing toward the front (toward your bike).
If the drive roller cannot reach the tire even if
you install the adapter, make sure you have been
installed in correct direction.
