GEAR MAINTENANCE
With use and especially while the bike is new, you may find the gears lose their smoothness
and can start to skip. This is a normal process as the cables and gears bed in. Below are
some basic instructions to assist with tuning.
A
GEAR TENSION ADJUSTMENT
If the gears are struggling to "climb" in to a lower
gear (bigger cog) after changing gear on the
shifter, then turn the barrel adjuster anti-
clockwise, out from the derailleur or shifter. Try
half a turn at a time and re-test. (This situation is
more common when the bike is new!)
If the gears are struggling to "drop down" in to
a higher gear (smaller cog) after changing gear
on the shifter, then turn the barrel adjuster
clockwise, in to the derailleur or shifter. Try half a
turn at a time and re-test.

ADJUSTMENT & MAINTENANCE - GEARS
When referring to gears, a lower gear is "easier" (bigger cog on the cassette)
and a higher gear is "harder" (smaller cog on the cassette). When you shift to a
lower gear, the shifter adds tension to the cable, pulling the derailleur to move
on to a bigger cog. When you shift in to a higher gear, the shifter releases cable
tension and the derailleur spring contracts, moving it in to a position for a
higher gear (smaller cog) and the chain follows.
