'77 Exxon Graftek Project

I've long been fascinated by older carbon fiber bikes, mostly the carbon tube and metal lug variety, and the Exxon Graftek was really one of the first on the market having been sold from the mid to late 70's which makes it all the more cool. My particular frame is from 1977 and features stainless steel lugs/drops, carbon/aluminum tubes, and a steel fork.

My goal has been to restore the bike to riding condition with a period Shimano build and a few modern components for comfort/availability. I debated for a while what group to build it with, I've seen a museum example that had a Suntour groupset, I had partial Campy group I could use, or I considered first gen Dura Ace. What sealed my choice on the Dura Ace was the black finish Shimano did for first gen in '78-'79. Its a beautiful groupset and perfect for this frame.

One of the biggest issues I had for this build was obtaining a seat post. These frames used a 23.8mm seat post which has just been impossible to find, there are a few older French frames that use this size but I never could find one available. The seat post currently on the bike is a modern manufactured 24mm post which I had machined down to 23.8mm.

The decals on the downtube were a little beat up as you can see in the earlier pictures. I found an NOS set of originals and have installed those.

Currently I am just waiting on a BB to begin final assembly. The NOS Dura Ace one I found in Germany went missing in the mail and I've not been able to source one in the US so I have a nice White Industries BB on order now.

I do get comments about the issues with these frames and how they come apart. I own a few of these bonded frames and am aware of how to inspect them and what to look/listen for while inspecting. After cleaning this frame up and having owned it for over 5 years now I believe at this time that the frame is still ridable but I do continue to monitor the frame's condition and have been working on a restoration plan should the worst happen.

Finished the build today and took some nicer photos of it. Still salt on the roads here but I'm hoping to get it out for a maiden ride soon.
