Picked up the Mixed 5D saddle recently. I have about 100 miles on it this week and I gotta say, this thing is awesome!
I donโt have any rides over 2 hours on it yet but I donโt see longer rides being a problem, although it is slightly firmer than I usually prefer, itโs shaped just about perfectly for my build and riding posture.

AI-Summary
The reviewer discusses the MIXED 5D saddle as one of three AliExpress saddles they use in their clinic. They describe it as extremely light and specifically recommend it for people with incredibly narrow pelvises and sitbone dimensions under 100mm. The saddle features a very flexible carbon shell, a massive rise at the rear, and tremendous clearance on the wings, making it good for riders who rotate their pelvis forward. However, they note the padding is not as good as 3D printed alternatives and that it is a bit delicate, having snapped on the inside edge from bearing weight on the front.

The reviewer provides a detailed analysis of the MIXED Full Carbon Fiber 5D Ultra Pack Light Weight Bike Saddle (referred to as the 'mixed fullcarbon 5D saddle' or 'mixed saddle'). They state it is substantially better than the previous saddles reviewed, with superior build quality, a more substantial feel, and a modern short-nose geometry. The top material is softer and grippier, and the carbon weave is visible on the bottom plate and rails, indicating a full carbon construction. It is very stiff with no flex. The reviewer found it comfortable on a 2.5-hour ride, praising its shape and the larger pressure relief channel. They note the saddle cover is still glued on, which is a cheaper construction method, but overall they are very positive. They rank it highly and explicitly recommend it as a great option.
