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.
