BB cup spacers
Step 4
Depending on a version of a product, most probably you will receive a BB with a spacer that is aached to the right BB Cup with grease.
It may be 2mm-thick (standard) or even 7mm-thick (for some folding bikes). This spacer posions gearbox further away from the frame,
to avoid a potenal collision - gearbox should not touch the frame other than:
1. with the reacon lever under the chainstay, as shown in previous installaon step,
2. around the BB cup ange. Any sideways contact gearbox<->frame must be avoided – if you noce it (please, check carefully),
use an addional spacer from the extras bag or reposion the lever like shown on this video:

On the other hand, adding spacers changes the chainline or beltline (important for belts!).
Cable-slider installaon
Step 5
If you use a rear derailleur with a shiing cable running along the chainstay,
you may need to avoid collision with the lever, by ulising a cable-slider with
a bolt (both to be found in the bag of extras). Standard frames have
a threaded hole in the BB shell prepared for this purpose.
S ier installaon
Step 6
GTRO is delivered to you integrated with the shiing cable and shier. Once the gearbox is installed on the axle, you must nd the best
way for the shiing cable. Please remember – GTRO shier is placed on the le side of your handlebar (like front derailleur’s shier)
GTRO’s standard shiing cable housing length is 110 cm for grip or trigger shier and 145 cm for the bar-end shier. It ts the majority
of bike’s frames. However, it may happen that you need a shorter or longer shiing cable – parcularly if you have a trike/recumbent
bike or a small folding bike. In this case, let us know what cable length would be the most convenient for you
GTRO’s shier is not integrated with a brake lever. If you have a front derailleur’s shier integrated with a brake lever, you need to replace
it with a separate brake lever. Choose one that ts your bike’s aesthecs from the bike shop
GTRO is oered with few types of the shier. Accordingly to the kind you ordered, please, do the following
Remove the handlebar grip (see hints ere or ere
Remove the exisng shier (if you have one
Route the shiing cable and x it to the fram
Place GTRO’s shier on the handlebar. Choose the right posion for your thumb and nger to operate with the trigger paddles and
adjust the shier to the handlebar. If you have a twist-shi, choose the correct posion, so that you can shi eortlessly between
the gears
Check, if the shiing cable is not colliding with or touching the wheel. Twist your handlebar in both direcons to be sure there is no
collision or excess tension on the wire
Put the handlebar grip back on.
