V270
instructions manual
Introduction
Thank you for purchasing the Minoura V270 indoor bicycle trainer.
The V270 incorporates Minoura's a new, patent pending technology on the ywheel that by design it
simulates 35% heavier (= more effective) than its actual weight.
The new NEODYMIUM magnet is 4x stronger than typical Ferrite magnets and offers a much wider range
of resistance from low to high all while providing equal step differentials to simulate real road riding.
The exclusive U-shape legs are lightweight but more stable than other trainers weighing much more.
And each leg can be adjusted +/- 10 mm individually to compensate for uneven surfaces.
Read this manual carefully and keep it for future reference.

Choose the pivot hole for your bike size on the
main pillar.
Once disassemble the pivot bolt.
Remove the alloy sleeve and plastic washers.
Insert the alloy sleeve into the selected hole,
and put the plastic washers on both sides.
Attach the U-Leg to the main pillar.
Check the plastic end plugs on the U-Leg are fully
inserted and aligned to the hole.
Then insert the pivot bolt and fully tighten the screw
with using the supplied M5 hex wrenches.
The center guide bolt is
intentionally loosened in
the package condition.
Tighten it slightly.
Check each leg moves
smoothly.
!You do not need to disassemble
the center guide bolt. Just tighten.

!Be sure you fully insert the plastic
end plugs to the U-Leg before
putting the pivot bolt through them.
Failure to do so will cause a
problem that the legs will not be
positioned in same height.

How To Install Mag Unit & Foot Step
Required Tools: 1 x 5mm Hex Wrench (supplied)
1 x 10mm Spanner (not supplied)
The Mag resistance unit and Foot Step now need to be
installed to the frame.
Attach the Foot Step onto the bracket on the Step-Bar rst,
put the Mag unit over the Foot Step, then tighten both
brackets together with the pivot bolt.
!Overtightening the pivot bolt will cause the
Foot-Step to become inoperable.
Make sure you unscrew (loosen) the pivot
bolt by 1/4 - 1/2 turn once you completely
tightened it.
The Mag unit should be lowered towards the
ground by its own weight at this point.
If the pivot bolt is too loose, the Mag unit
will drop quickly and you may be pinched
between the frame and Mag unit.
Adjust the tightening torque for the best
operation.
If you need to adjust the Mag unit position horizontally
to set the tire in the center of the drive roller, loosen the
backside screws and slide the Mag unit sideward.
After adjusting, tighten both screws rmly.
If your tires is a 26" and smaller than 1.50" in width,
you will need to use the supplied Z-shaped Small Wheel
Adapter.
(The tire size is clearly indicated on its side wall)
The direction of the Z-adapter is xed 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, make sure the
Z-adapter has been installed correctly.
Use the original cap head bolts for the Mount Base, and
use the supplied hex head bolts for the Mag unit.

Placing V270 on Floor
Fully open the legs and place on a at and horizontal oor.
!To open the U-Leg, grab the main frame and the rubber cap on the U-Leg.
Do NOT pull the Alloy Leg Guide directly, otherwise it may be bent or damaged.
Check that all 4 points are touching the oor
evenly.
If all 4 points are not touching the oor evenly,
the frame could be deformed and cause damage
to the trainer and possibly your bike.
About Leg Height Adjuster
Each U-Leg height can be adjusted separately by
+/- 10 mm travel.
This adjuster allows for uneven oor or ground
compensation to help insure proper stability.
When using the adjuster, be sure to check and make
sure that all 4 points are touching the ground evenly.
And the trainer should be positioned as close as
possible to the oor for better stability.

How To Mount Your Bike
V270's coupling position is pre-adjusted in the factory to t the 125mm standard rear hub width.
If it is too loose or too tight to your bike, or if you use different width of rear hub like a track race bike,
adjust the left side coupling as precisely as possible for maximum stability.
Please note there is no adjustment on the right side (lever side) coupling.
!The coupling cone shape is designed to t the supplied quick release skewer perfectly.
We strongly recommend you to replace your rear wheel skewer to the supplied one.
We do NOT guarantee the stability while using V270 with your own skewer.

First, loosen the red Lock Ring by
turning it counter-clockwise.
The left side coupling is actually a bolt/
coupling combination.
Turn the coupling to adjust the position.

Raise the Quick Hub Clamp Lever up to
retract the right side coupling.
The following steps describe the micro adjustment of the left side coupling. This step is not always
required and once xed in the proper position, you should not need to adjust again. Once adjusted
to t your bike, simply operate the Quick Hub Handle Lever for a proper t every time.
Insert the left side hub end (quick release
lever side) into the left side coupling cone.
In this position, place the other side of
the bike into the right side (rear cog side)
coupling cone. Make sure your derailleur
cable goes OVER the coupling.
Now, push down (lower) the Quick Hub
Clamp Lever until it fully engages the
skewer or axle nut.
Make sure the Quick Clamp Hub Lever
is lowered into its locked position and
cannot be lowered any further.
The frame may appear slightly open but
this is normal.
If the frame seems to be opened too
widely, re-mount your bike following
the instructions. Failure to do so could
damage your bike and/or the trainer.
Now, grab the saddle of your bike and rock the bike back and forth to make sure your bike is securely in
the trainer. Your bike should not move independently of the trainer where it is attached.
Tighten the red Lock Ring rmly to x the left side coupling position.

!If your bike's rear hub axle is NOT a quick release skewer type, but a hub nut type,
you don't need to use the supplied skewer and replace the left side coupling bolt to the
optional one; "Left Side Coupling Bolt for Fixed Hub Nut".

How To Use Foot Pedal
The Foot Pedal is a convenient device to engage/release the drive roller to/from the rear tire quickly, and
it keeps the proper pressure of the drive roller to the tire without adjusting everytime you use the V270.
To maintain the tire life as long as possible, you should adjust correctly.

To engage the roller: Push down the pedal
To release the roller: Pull up the pedal
!While we call this a "Foot Pedal", we do not recommend you use your foot to operate it.
For accurate adjustment, please use your hand.
How To Maintain Proper Roller Pressure
5
Lift up the Mag unit towards the rear tire until the
clearance between the tire and roller is about 2 mm.
In this position, turn the red adjust knob under the
Foot Pedal clockwise until the inside bolt touches the
black steel base plate.
At this point, stop tightening the knob and gently but rmly
push down the Foot Pedal to engage the tire to the roller. It
is normal that the tire is compressed by 3-4 mm. Adjust the
knob if the contact is not too much nor too little.
Now, hop on your bike and give it a spin. If your tire slips, tighten the knob in 1/4 turns until the contact
is correct. If the tire drags or you smell burning rubber, back off contact in 1/4 turns until you achieve
proper contact.
!If the roller pressure to the tire is not adjusted properly, premature tire wear can be
expected. Too little pressure is worse than too much pressure for good tire life.
6If always using the same bike and tire, no further adjustment should be needed than operating the pedal.

How To Operate Remote Shifter
V270 comes with a convenient remote shifter device. By installing it on your handlebar or stem,
you can adjust the resistance level in 7 levels without getting off the bike.
The remote shifter should be used in conjunction with the gears on your bike to achieve maximum
efciency in your workout.
How to install the remote shifter
1) Wind the soft fabric band around the handlebar,
2) Hook the metal ring to the gutter on the plastic shifter base,
3) Flip up the lever to lock.
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.
The remote shifter is pre-adjusted to t 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 fabric band length.
TIPS: At this moment, you should pull down the guide pin for
easier job to loosen the band.
How To Adjust Remote Cable
If you cannot shift at L or H position, it's time to adjust the remote cable.
1) Set the remote shifter lever at "H" position and straighten the cable.
2) Pull off the black plastic cap on foot of the cable, then the adjusting screw will appear.
3) While pushing the outer cable toward the shifter, push the adjusting screw to the outer cable.
4) Turn the lock nut until it touches the Mag unit.
5) Insert the plastic cap again.
