History of Campagnolo
Campagnolo Super Record was released in 1974 as the successor to Campagnolo’s top tier group set, Nuovo Record. The Super Record group set was in production from 1974 to late 1980’s. During this period, Campagnolo released 4 different versions of the Super Record seat post (or the ‘seat pin’ as it is referred to in their literature). The first version featured a 2 bolt clamping system whilst the later versions all featured a single bolt clamping system.
First Version (circa 1974 to 1978)
(1973-1978)
The first version featured 2 bolts mounted on top of the clamps to fasten the saddle rails. The saddle tilt is adjusted by tightening one nut and loosening the other.
This post is similar to the Nuovo Record seat post that preceded it, but it can be easily identified by the lovely elongated flutes which are present on the upper section of all 4 versions of the Super Record seat post.
The upper section is cast alloy and the post is polished alloy. Unlike other components in the group set, the seat post is not anodized and can be restored by polishing.
Second Version (circa 1978 to 1982)
The second version was a simplified single bolt saddle clamping system.
The bolt was relocated to underneath the clamp which made it much easier to adjust or removed the saddle.
The clamp sits on a curved top section of the post to allow the saddle to tilt fore & aft.
You will also notice the upper portion of the post is now tapered and polished.
Third Version (circa 1983 to 1984)
The third version utilised the same single bolt clamping system as the previous version, however the tapered upper portion of the post is no longer polished and the text and flutes were moved further down the post.
All 4 versions of the post appear to have ‘BREV. INTER. CAMPAGNOLO’ engraved at the top of the post.
Fourth Version (circa 1985 to 1987)
The final version of the Super Record post is nearly identical to the third version, however the upper section of the post is now completely polished to give it a nicer finish.
All seat posts are marked with a minimum insertion LIMIT marking.
Dimensions & Sizing
Seat Post Saddle Clamp Parts
The Super Record seat posts were available in 2 different lengths; 130mm (standard) or 180mm (long). A quick check on eBay shows that most of the second hand and new old stock posts are the longer 180mm version which gives you a few more options regarding frame sizing. Bear in mind that whichever post you choose, approx. 55mm of post must be inside the seat tube of the frame.

Campagnolo offered the seat post in no less than 10 different diameters;
25mm, 25.8mm, 26mm, 26.2mm, 26.4mm, 26.6m, 26.8mm, 27mm, 27.2mm & 27.4mm
You can see in the above photo that the seat post diameter is marked on the top rear section of the post. It is important to use the correct diameter post in a steel frame to ensure it doesn’t slip down when riding. From my experience, a greased seat post will be a firm fit in the seat tube of the frame. My 1984 Colnago Master requires a 27.2mm seat post.
Problems with a Single Bolt Clamp Design
Whilst the single bolt clamping system is easy to use, I have experienced problems with the saddle nose dropping down during riding. I found this was due to the saddle clamp slipping on the curved top section of the seat post.
Initially I cleaned all the clamping parts (except the bolt threads which need to be greased) and tightened the bolt up firmly, but the saddle nose was still dropping on just one ride. Whilst the clamping bolt is steel, the threaded top clamp is only alloy, so I didn’t want to over-tighten the clamping bolt for fear of stripping the threads, but it could be a case of me being over-cautious.
After searching online, I decided to apply some carbon paste to the underside of the saddle clamp where it contacts the top the seat post. I tightened the seat post clamp bolt to 22Nm. So far this has worked to keep the saddle in position, but I will update this after a few more rides.
