Campagnolo Centaur / Euclid / Olympus left and right bottom bracket cup set, hailing from Italy and in production from the 1980s to the 1990s (yet still new & unused after all this time). Made from steel and weighing in at 85 grams (for the pair). A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.
The spec of these cups is the same as other Campagnolo mountain bike ones from the same era, so they're also compatible with other models such as Euclid, Olympus, Icarus & Contax.
OVERVIEW
TECHNICAL INFO
Bottom Bracket Type - ‘square taper’, as the name suggests have square shaped axle ends that slot into the chainset and ‘cottered’ axles are round and secured by pins - pretty much every bike up until the 1990s would use one of these, cottered being the much earlier system.
Thread Type - this must match the bottom bracket thread on your frame. The 3 common thread types on classic and vintage bikes are English (also known as British or ISO), Italian & French, and are usually (not always!) found on frames built in their respective countries. If you're replacing cups, they often have the thread type stamped on one of them, if not there are a couple of things to look at; bottom bracket shell width (English & French = 68 mm, Italian = 70 mm) & drive side cup thread direction (English = left, Italian & French = right). The only curveball to watch out for here, although pretty uncommon, are Swiss threads (also found on some French frames, Motobecanes being one) which will have the same shell width & thread direction as an English thread frame but the actual thread pitch will be different. If none of the above matches what you have, there are a few lesser known varieties that will require some further research.
