ThirdCog...in my humble opinion, leave as much original as possible. Actually, EVERYTHING if you can! This model is not the typical CANNONDALE model that has upgrades done to it for various reasons. It's a limited run, no matter what year it was made, and finding original black parts for it is like finding hens teeth.
If you want to tinker...do it to a regular CANNONDALE model. There are tons out there. But leave the Black Lighting original.
