Most vintage bike enthousiasts know that there are 2 types of super record seat posts, the 2 bolt design and the single bolt design also known as the second gen. Surprise, the second gen has 3 variations, very small differences just like the c record first and second gen seatposts and headsets.
1: 1973-1978 based on the superleggero (or nuovo record superlight) seatpost with alloy shoulders for the saddlerails and the well known indistructible steel clamps, machined bushings and the typical campy bolts, notice the elegant letters of the campagnolo logo that go around the seatpost, not like the nuovo record with the worldlogo on the front.
The flutes are also really subtile not like those homemade seatposts you see done by people themselves. The upperpart is casted alloy, the lower pard is machined and polished (the one in the picture has been restored).
2: 1985-1987 “brev inter. campagnolo” stamped on the shaft, matte saddleclamp.
3: 1978-1982 “brev inter. campagnolo” stamped on the tapered piece of the seatpost, the clamp is polished and anodised.
4: 1983-1985 fully polished seat post, matte saddleclamp.
The material campagnolo used for the seatposts was rather soft alloy for etter dampening and comfort but this aluminium is not very strong against corrosion so we often see seatposts that are stuck, especially if the flutes were deep enough to be in the frame, when riding in the rain the water gets in the frame trough the flutes and everything starts oxidising.
Mounting guidelines for the First gen
- to put the saddle into the correct position requires special tools and still isn’t easy to accomplish
- just like the superleggero seatpost the spall rings on the clamp intend to break if your weight is too high (I would not recommend riding this seat post if you are +85kg) (see the pictures for most common crack areas).
Mounting guidelines for the Second gen
- if you don’t handle the clamp bolt with care and the right tool it will wear out
- If you tighten it without grease or too hard the threads will vanish, I provided a picture of a simple solution called a “helicoil” it is used a lot in the automotive industry to repaire spark plug threads
- If you put too much force on the clamp, it will crack. I provided pictures of the most common areas where the clamp may fail
