/Cycling Colnago Build-up, Phase I

I spent some time yesterday preparing my new old Colnago frame for the eventual build. Tasks completed:

  • Pulled the bottom bracket. Had to take it to the shop to get the right side pulled. Note to self: Italian-threaded bottom brackets are right-hand threaded on both sides, regardless of what your crappy service manual says.
  • While at the shop, got a Campy seatpost binder to replace the ugly bolt that was being used by the previous owner.
  • Pulled the brakes, and washed the frame and fork, taking note of all the scratches and worn spots. The cleanup itself resulted in a better looking bike.
  • Washed and lubed the brakes.
  • Took a bunch of detail photos.
  • Bought and applied touch-up paint. Luckily, the worst paint dings were in the black sections of the paint job, so I fixed the worst dings with black metallic model paint. It seemed to be a pretty decent match. I also applied fresh white paint to the clover logos on the down tube lug and rear brake bridge. I didn't have the courage to attack the more detailed white-filled areas of the frame such as the seat stays and fork crowns.

Today, I took the above pictures. I noticed while manipulating the bike, that the 26.8mm seatpost (the size that the eBay seller said this frame requires) didn't seem very tight -- it was very easy to rotate the bike on the seatpost while it was clamped into the stand. so, I tightened it a bit more. I could still move the seatpost, even by hand. Looking at the expansion slot in the seat tube I could see that it was completely closed. So, I tried putting a 27.2 seatpost in. No dice. I put the 26.8mm one back in and bore down on the shiny new Campy binder bolt, and promptly snapped it :-(. Another newbie mistake. Now I'm left wondering what the hell seatpost size this bike actually is. I'm guessing it's actually designed for a 27.2mm, and I've compressed it a bit by screwing it down onto a 26.8mm. It would help so much if I knew the actual model and year of this bike.
