How To Mount Your Bike
TWIN's coupling position is pre-adjusted in the factory to fit 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 fit 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 TWIN with your own skewer.

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

Raise the Quick Hub Clamp Lever up to
retract the right side coupling. (Fig. P)
The following steps describe the micro adjustment of the left side coupling. This step is not always
required and once fixed in the proper position, you should not need to adjust again. Once adjusted
to fit your bike, simply operate the Quick Hub Handle Lever for a proper fit every time.
Insert the left side hub end (quick release
lever side) into the left side coupling cone.
(Fig. Q)
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. (Fig. R)
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 firmly to fix the left side coupling position. (Fig. R)

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".
