How difficult is it to install the WHEELTOP EDS, and what tools do I need?

Installation is straightforward for users comfortable with basic bike maintenance—you'll need a Phillips screwdriver, Allen keys, and a chain tool to remove your old derailleur and install the WHEELTOP EDS in its place. Most riders complete the installation in 30-45 minutes, though first-time installers should allow an hour and consider having a shop handle calibration if you're unfamiliar with derailleur adjustments.
