GYRO V270
instructions manual
Introduction
Thank you for purchasing the Minoura GYRO V270 indoor bicycle trainer.
The V270 incorporates a new, patent pending Gyro Technology ywheel that by design is 35% more
effective than other trainers in its class.
The new NEODYMIUM (neo-dee-um) magnet is four times 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 to compensate for uneven surfaces.
Read the is manual carefully and keep it for future reference.

How To Install Mag Unit & Foot Step
Required Tools: 1 x 5mm Hex Wrench (supplied)
1 x 10mm Spanner (not supplied)
The GYRO Mag unit and Foot Step now need to be
attached 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 GYRO Mag unit should be lowered
towards the ground by its own weight at this
point. If the pivot bolt is too loose, the GYRO
Mag unit may drop quickly.
Adjust according to directions for 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 1.75" in width, you
will need to use the Z- adapter (supplied).
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 can't 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, hold the main frame and the rubber cap on the U-Leg.
Do NOT pull the Alloy Leg Guide directly, otherwise it will 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 bend causing damage to the
trainer and possibly your bike.
About Leg Height Adjuster
Each U-Leg can be adjusted separately by +/- 10
mm. The 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.

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 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 right side coupling adjustment.
!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 if you use your own skewer.

First, loosen the 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 ride side coupling cone.
This is the derailleur side. 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
and this is normal. If the frame seems to
be opened 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 lock 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. Make sure the nuts of your axle t into the
couplings securely.

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 engage/
disengage it. For accurate adjustment, use your hands!
How To Maintain Proper Roller Pressure
4
Lift 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
Mount Base.
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 for the tire to compress by 3-4 mm.
Adjust accordingly if the contact is too much or 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 is not adjusted properly, premature tire wear can be expected.
Too little pressure is worse than too much pressure for good tire life.
5If always using the same bike and tire, no further adjustment should be needed.

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 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 0 resistance. There is still some resistance at "L".
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.
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.
2) Pull off the black plastic cap on foot of the cable, then the adjusting screw appears.
3) While pushing the outer cable toward the shifter, push the adjusting screw to the cable.
4) Turn the lock nut until it touches the Mag unit.
5) Insert the plastic cap again.
