Trying one for the first time. No padding! I do not do long rides, 30-45 minutes typically. I’ve done three rides with it. It’s actually not terribly unpleasant! Featherweight at 115 grams. I’ll probably switch back to my padded saddle if and when I do a longer ride.

My minimally padded Repente Quasar CR 2.0 is only 5 g heavier. However, it is only 260 mm long.

Same experience here. Although after a few rides on something similar I've decided they are to be reserved for photo shoots and targeted hill climb efforts only.

This one is 270mm long by 143mm wide.

The Quasar CR 2.0 is 260 mm x 142 mm, whereas all of my other saddles are 275 mm long. I don't miss the extra 15 mm length, but I cannot go any shorter; no 245 mm snub nose saddles for me. This saddle will probably work for you if you want to ride > an hour.

Switching saddle depending on your ride lenght...no thanks.

Very good looking though, but I prefer some padding to absorb my arse even if it's heavier.

Biker Pete 

My other saddle is mounted on a seatpost so switching it out will be easy. But…..the jury is still out on this saddle, I’ll decide after a few more rides….

I bought something like this on Amazon for $10. Plastic fake carbon look. It's a bit flexible and actually super comfortable. I'm not sure how long it would last, though.

I have been on bare carbon for 18 yrs. The most comfortable saddle I have owned. Almost all daily weekday 50mi rides. Carbon saddle wings flex but they need to fit the body.

classic Selle SLR was 135g, padded too

I did the bare saddle for awhile, but I prefer some padding on the bumps. I picked this up from AliExpress for under $50 USD. It has sturdy carbon rails, a stiff carbon shell and cushy 3D printed mesh for padding. Weighs a bit more at 150-160g, but the 3D mesh always maintains it's cushion and it stays cool even on the hottest of days since it doesn't absorb heat.

But probably super narrow just for pros with tiny hips, right?

My three other Selle Repente saddles (Artax GLM, Spyd 3.0, and Prime 3.0) are 142 mm wide and weigh just over 160 g each, and my Selle Italia SLR Kit Carbonio Superflow is 145 mm wide and weighs just under 160 g, so it seems that 160 g is the happy medium for a regular-length, minimally padded saddle.

maybe? not sure. I like the SLR so far. I'm a smaller rider at 5'9" and 145 lbs. Category 2 and active Master's racer.

I also have a couple of old school Selle Italia Flites around too - now those are comfortable. I think they're wider? IDK

I tried a pure carbon saddle once, I had to make it myself. Quit using it because it left marks on any pants I rode with that were not pitch-black.

It could have been worse; your home-made saddle could have cracked, landing your gooch onto the seat post and/or the saddle rail clamp bolts.

Every time I read a thread about ultra-light all-carbon saddles I am reminded of the first time I saw one of those ~70g wonders on a group ride. I asked the owner "Is that thing comfortable; like, can you ride all day on it?"

His response was "All day, sure. But the next day, forgetabout it!"

I've the op's saddle for several years. Personally find it comfortable and often do 100km rides.
Once a car crashed into me, hitting me from the side on my hip, which in turn compressed the saddle between my legs. I'm glad I had this saddle, because the carbon flexed, instead of breaking up in my nether regions! As for the bike, a carbon Colnago CX-1, it broke in two and the carbon cut my knee up.
Anyway, I'm one of the few that actually like those saddles.

Biker Pete 

Ouch! That’s an experience I hope never to have!

I bought the bike used, a 2016 Kestrel. It came with an Oval Concepts carbon seat post and Prologo saddle. I got this new RXL carbon saddle and also an RXL carbon seat post. I cut off 8.5 cm of excess on the new seat post. So the new saddle and trimmed seat post saved a whopping 230 grams compared to the original saddle and seat post.

I have one of these on a vintage Schwinn bmx bike that I ride in the driveway and at the school ground with my kids. It's better than the oem rock hard plastic seat the bike had. A friend bought one for his road bike and it only lasted a few hundred miles.

Jack Tone 

So far mine's lasted over 1000 miles on some pretty rough roads and I'm well over 200 pounds, so I'm pretty pleased with it.

The only pure carbon saddle that has tempted me is the Selle Italia C59 at 59g but to be frank there are simply more comfortable saddles at 115g or close to it. A Prime Primaversa Carbon Road saddle with padding is 132 and $120. A Bontrager Aeolus RSL is 142g but has foam padding.

Don't get me wrong I am super tempted to get a Berk Lupina Padded which is like 100g, but my $120 Prime Primavera Shorty at 170g and $120 Prime Primavera Road saddle at 132g are super comfortable and a fraction of the price while still be light

How long was that post before you cut it, and how much post is in the seat tube?

Biker Pete 

I cut it so that there is about 1.5 inches extending below where the top tube intersects the seat tube.

choddo

The assumption being that there’s only about 1.5 inches of full diameter post on the bit you cut off below the minimum insertion point so as long as you leave that much, it should be fine? Ok well good luck. I honestly thought your photo was a joke at first.
