I know I am new-ish around here and there is a lot more acceptance of replica frames here than in other places. However, I don't really understand the point of adding a UCI logo to non-approved frame unless the point was go beyond adding the Cervelo logo on the HT to convince people that this is a real Aspero 5 or convince a race judge that this is an approved frame for use somewhere.
In general, I love the idea and geometry of this frameset. It's too bad IMO that they copied the downsides of this frameset along side the good things. I would have loved to see an aggressive gravel race bike like this or an all-road bike that used a round tube steerer, 52mm bearings lower and upper and a t47BB, either an asymmetric one or a normal one.
Bro chill out. Fuck UCI, this sticker means nothing even if it is original. It tells nothing about the quality of the frame, it's not like some iso certificate or something. In order to get it frame producer, just needs to pay to this greedy organization and the frame dimensions need to be within UCI rules. They don't care about the quality, just about their rules.
Anyway, gravel scene hates UCI and wants to stay away from this corrupt body as much as they can, so that's the bigger reason for not putting this sticker on the frame. But if the owner wants to do it? It is his choice mate, because this frame checks all to boxes of the rules. The manufacturer just did not pay the bribe. It's not like he is putting fake specialized, cervelo, trek sticker.
