The reviewer discusses purchasing a carbon seat post from AliExpress to replace their old aluminum seat post for weight reduction and better comfort while riding. They mention choosing a seller with high positive feedback and note that the shipping was surprisingly fast (19 days). The seat post comes in several sizes, and they purchased the 27.2 by 350 millimeter version. They highlight the low cost (approximately 19.28 euros) and compare it to a more expensive Deda model, noting the similar shape and fittings. The reviewer is pleased with the appearance, weight (193 grams compared to the original 327 grams), and finishing of the seat post. They also mention the two-screw assembly system and the roller details, which they appreciate. However, they caution about the risks of using unbranded or untested products and advise consulting a qualified bike mechanic.
