3D Printed Bike Saddle, 143mm Full Carbon Fiber Bicycle seat - 7 * 9mm Carbon Rails - Adaptive Bicycle Seat for Mountain Road & Gravel Bike

It’s shorter than most saddles. It didn’t effect me but might effect someone else. I rode 42 miles with it so far. Worked out pretty well!

I installed this seat on my Stages SB20, a stationary trainer. Stationer trainers can be tough for comfort since they don’t move with your body. I’d originally bought this seat since I had good luck with the Ryet 3d carbon fiber seat. This seemed similar, and had a deal available for Black Friday.Essentially they print more layers where more padding is needed. So it’s dynamic depending on where you sit. Once I got situated, my seat bones locked in nicely to the 3d honeycomb structure. I could feel the seat gently moving to the left and right with pedal strokes which definitely helps to reduce fatigue.The seat has oval rails which were not a problem for my application, but might not fit your seat post if yours isn’t compatible with oval rails.The finish is bright and glossy and shows the carbon fiber underneath. I believe that it might be considered a 3K weave. I could be wrong. The point is that it’s glossy as opposed to a matte or opaque finish.I spent 1:40 on this saddle today and it felt great. Given the price, I think it’s a great value. There is literally no reason to spend hundreds on a 3d printed saddle when all you’re doing is buying a name. The quality is sufficient for the price and the function is excellent.I would recommend this saddle to a friend.

Good seat, but it tends to crackle a bit on bumps. Seems to be solid, but the crackling is a bit concerning.

I bought this saddle as an experiment, to see how well these inexpensive clones actually work and how well they are made. So far I have been pleasantly surprised. The saddle is comfortable (to me! saddle shape is very personal), having a good amount of give in the cushioning and some flex in the shell. (This is not an uber-stiff carbon fibre saddle, so if you are looking for that you will be disappointed). The padding varies in stiffness across the saddle, which seems to work quite well. I have ridden several multi-hour rides so far, and so, while the jury is out on long-term reliability, it has served well so far and been quite comfortable - as comfortable as the best saddles I have owned, in fact.One potential problem for some folks is that the saddle appears to not be formed perfectly symmetrically - one side droops ever so slightly (maybe 2mm). For me this is a non-issue, as the spots where my sit bones are supported is not affected, but for highly sensitive riders, or riders with a different "seat physiology", it might be problematic.

My issue with my last saddle was that I could feel my sit bones for 24 hours after every long ride. Not pain, just something I would describe as an afterglow. I’ve gotten skinnier as I’ve gotten older and there’s less padding, and the last saddle didn’t have much either. I’ve been looking at Fizik and Speciakized’s honeycomb saddles but they’re so damn expensive. So I thought I’d try this because, you know, Amazon so you can return it if it doesn’t work out. So I’ve done a couple of rides so far, a 20 and a 30-miler. And each time I’ve got off the bike with absolutely zero “afterglow” in my sitbone area. Just your normal nothing-special ass. I’ll update this review once I’ve done a few longer rides.Update: 5,000 miles later I can unreservedly recommend this saddle. I ride a decent amount (100+ miles/wk) and I have absolutely no problems with this saddle. In fact I never think about it because it’s so perfect for me, which is probably the best thing you can say about a saddle — it does its job so well you just don’t notice it. This achieves that. For me personally (and all our bodies are different) I don’t think I could find a better-fitting saddle for five times the price of this one. I should actually buy another one now that I think about it in case of any damage.

Looks good and almost as light as specified (actual 185g), but not much padding beyond the fairly uniformly thick 3d printed material. Also had a couple of hard spots around the cutout that seemed like they could hurt.Initially impressions were ok, though the saddle was harder than expected. Went for a 40 miler and was ok for the first 10, but by the halfway point I was in pain under my sit bones. The padding (really just the 3d cover) was simply too thin. I also noticed the carbon shell a had zero flex.Added up to major pain and a couple days off the bike. Still a bit sore a week later.Immediately switched back to my old saddle (Fizik Antares) and have just upgraded to the adaptive version of that saddle. That has the 3d printed cover, some decent flex and actual dense padding under my sit bones.I realize our anatomy are all unique to some extent, but I’d recommend other saddle options given my experience.

How the warranty works? Mine cracked at the mold in the middle, see attached pic.

A nice sturdy seat reasonably comfortable
