Drive train
Check that the cranks are tight after the first 50 miles
of riding. These should be fastened firmly to the bottom
brackets, with no play. Even a small amount of movement
will cause the joint between the spindle and the hole in
the crank to wear, resulting eventually in damage to the
chain set.
The rear derailleur idlers tend to collect oil and dirt.
Clean them with a dry rag. If they squeak, they can be
disassembled and greased. When you lubricate your
chain, put a drop of light oil on the moving pivots of the
derailleur; they will last much longer. The more you ride
your bike, the more used you become to the sounds it
makes. If you notice any change in the sound your bike
makes, check it carefully; it may be a sign of something
needing attention.
Handlebars/stem
Both stoker and captain handlebar arrangements, which
include the stem and quick release steerer extender,
should be checked before every ride. The careful
operation of the quick release steerer extender is critical in
ensuring that it continues to function correctly.
The steerer extender fits to the top of the fork and locates
on the 4-pointed star, the slot at the back of the extender
should align with the vertical slot on the side of the top
cap when the handlebars are pointing forward. Ensure
the steerer is fully pushed down before tightening the Q/R.

Headset
The headset is the bearing which allows the fork to rotate
in the frame. It plays a major part in the handling of the
bike and should be checked regularly (as per table);
that it's both tight (not rocking front and back when front
brake is applied and bike rocked backward and forward),
and turning smoothly. If you are unsure about adjusting
your headset, consult a qualified mechanic.
Quick release and thru axle
Quick-releases are used in a number of places on your
bike; it is important that they are tightened correctly.
To locate a quick release properly, adjust the quick-
release by opening it, holding both ends and turning one
clockwise until, when you close the lever, you feel some
resistance. At this point, try to close the lever fully. The
adjustment is correct when you can fully close the lever,
but with some effort (the lever should leave its impression
in the palm of your hand). If you can only close the lever
part way, open it, unscrew the adjusting nut slightly and
try again. If it closes too easily, tighten it up a tiny bit and
try again.
Open
The front wheel is held in place using a thru axle, which
can be installed/removed using a 6mm Allen key, from
the left side (disc brake side) of the fork.
