movement. Periodically, inspect the handle-post
to ensure that it is properly adjusted.

CAUTION:

Do not attempt to ride your bicycle with a
loose handlepost hinge. If when you close
the handlepost hinge and then close the
hinge latch, it appears loose or requires too
much force to close, the latch may need to
be readjusted.

Dahon Neos Derailleur

The low-profile Dahon Neos derailleur was specially designed for small-wheeled bicycles. The
Neos allows much more ground clearance than a conventional derailleur. Using cache technology,
it permits the derailleur body to lie flat underneath the chain stays. This way the derailleur body only
projects 12mm from the chain stays and is much more protected than a standard derailleur, which
protrudes up to 40mm.

Due to its special design, the Dahon Neos
