Campagnolo Gran Sport seatpost, hailing from Italy and in production from the 1970s to the 1980s (yet still new & unused after all this time!). Made from aluminium/steel and weighing in at 265 grams - pretty lightweight for seatposts at that time. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.

If you're taking part in L'Eroica or a similar vintage event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong seatpost!

Please note: Once inserted into a frame this cannot be returned, so please make sure to double check the diameter is correct before installing.

Seatpost Diameter - this needs to match the internal diameter of your frame’s seat tube closely, it should be possible to insert the seatpost without force but the fit should be tight enough so it doesn’t just drop in, with no play once inserted. If you have a post that fits the measurement should be stamped somewhere near the bottom, if not you’ll need to measure with a caliper or seatpost sizing tool as the sizes go up in 0.2 mm increments.

Length (Centre of Rails to Base) - measured from where the centre of the saddle rails will sit once installed, all the way to the bottom of the seatpost. Normally there’s a mark to tell you how much of the seatpost needs to be inserted in the frame, however this isn’t always the case so we’d recommend allowing a minimum of 6 cm.
