Campagnolo Super Record was released in 1974 as the successor to Campagnolo’s top tier group set, Nuovo Record. Referencing Campagnolo catalogue 17a (circa 1975), the seat post bolt was available in either 8mm diameter (part number 1072) or 10mm diameter (part number 1070).
However, in Campagnolo catalogue 18 (circa 1983), the various group sets were only supplied with the 8mm diameter bolt. The same seat post bolt was supplied in all the different Campagnolo group sets.
Fitting & Materials
According a 1981 UK retailer catalogue I found online, the bolt is made from chrome steel, but you need to be careful not to overtighten the bolt or it can snap. If the seat post is the correct diameter for your frame, you shouldn’t need to overtighten this bolt. The seat post should be lightly greased.
When fitting the part, you will notice the nut has a knurled end. I fit the nut to the left side of the frame on My Colnago Master, and insert the washer and bolt on the right side of the frame.
You will need 2 x 5mm Allen keys to tighten or loosen the bolt in the frame. Use an Allen key on the left side of the frame to hold the knurled nut secure so it doesn’t move. The Allen key on the right side of the frame is used to tighten or loosen the bolt (threaded part). The threading is standard (clockwise to tighten, anti-clockwise to loosen).
Internal width when both parts fully threaded together: 18.5mm.
Internal width when both parts barely threaded together: 28mm.
Internal diameter: 8mm (or 10mm as mentioned earlier).
UK Pricing in 1981
I found a 1981 catalogue for a British cycling shop with pricing as follows;
The Campagnolo seat post bolt retails for GBP 1.80
Super Record Component Weight
I have weighed a set of Super Record components and quite surprisingly, these vintage parts compares quite favourably against the weight of a modern Campagnolo Super Record group set.
