Save the Frame
I’m restoring an older Cannondale 3.0 series aluminum frame. I know that with steel frames you want to use Frame Saver or the like on the inside tubes. Does one do anything similar to an aluminum frame? When I pulled the bottom bracket on the Cannondale, there was significant galvanic corrosion that I’d like to avoid the next time around…perhaps just a liberal coating of grease?

We have a good following of Cannondale Crit lovers here that would like to see your project as it develops. Post up when you can.

Here's a pic of the bb AFTER scraping out most of the corrosion and soaking for a couple of hours in vinegar. My guess is water got into the BB shell and it and the BB reacted. Removing the BB, I broke the tool because it was so frozen in there. On the plus side I was able to source a replacement for the missing derailleur drop out.
