TECH TIPS
• For a full outer model, operate the lever normally, move the front derailleur
several times, and then remove the initial extension. After removing the initial
extension, secure the cable in place and then adjust.
NOTICE
• Remove the initial extension before installing the chain.
• If a chain is already installed, turn the crank as you operate the lever.
