Thanks delicious. It wasn't just the coke that was acidic enough. The coke only took care of the upper layer of rust, say the rust that was ON the bolts. The corrosion that went into the bolts had to be removed by sanding. Unfortunately, that made some scratches so I had to wetsand afterwards, and polish after that.
As you can see I decided to make the letters black after all, instead of red. Keeps it just a bit more subtle, especially since there's no red in the bike whatsoever.
After I was finished with the calipers I thought I'd get some more work done. I took care of the seatpost. It's still the original seatpost and I'm planning on keeping it. It still works fine, even the 'head' is still intact, which is remarkable, since it's dated 1986
First I took out the post and noticed some old, very old grease/paste.
Obviously, that had to go. After spraying it with some aggressive grease remover, I waited for about 10 minutes and thought I'd be able to wipe the grease off with a paper towel. Not a chance!
I took a 'sanding sponge(?)' and rubbed it till the grease was gone. But still, some nasty muck was packed up in the very, very, very tiny grooves in the seatpost. I took care of that with some very fine sanding paper.
Right now it looks much better, though over the years some small visual marks have packed up on the post. It's ok, it shows character imho.
Since I was actually very pleased with the subtle detail on the calipers, I thought I'd give the seatpost a shot as well. Here it is, with the SR Laprade letters colored in.
In this picture you can as well see some of the visual marks on the 'head' of the seatpost. Luckily, that won't be visible when the saddle's on.
Just a question. I found a Brooks (most likely a Flyer) saddle on the web for a very low price. It's in a used condition so it has some marks on it, but still looks pretty good. Since the bike will be sort of a Randonneur, I thought it might be quite a nice saddle for this bike.
Two questions, maybe you guys could give me some response on this.
Q1: When using the bike as a Randonneur, will the geometry be just fine to use a Brooks Flyer, or should I rather go for a B15/B17?
Q2: Will the value of the bike increase a lot if I mount a Brooks? They're great saddles, this I know. But is a bike with a Brooks actually worth a lot more?
