Front Derailleur Cable Routing
To keep bike shipping boxes within shipper size limits, a certain
amount of disassembly is required. On most 'bents with an adjustable boom,
we remove the entire boom/crankset assembly which requires disconnecting
the front derailleur cable. A common reassembly mistake is improper front
derailleur cable attachment - we've even seen other bike shops do it -
*gasp!* The correct way is shown below.

On Shimano bottom pull derailleurs it is important to note that the
cable runs UP
AND OVER the leverage tab. Many people make the mistake of
using the leverage tab as a cable pinch by running the cable UNDER the
leverage tab - this changes the pulling leverage of the front shifter and
makes it impossible to properly adjust the front derailleur.
