I currently run the HBR17 on my LCG071 as a Gravel setup, works perfectly fine for me, also on gravel.
I ordered a 100x380. They measure exactly 380(c-c). Also they measure 100 in length. Measurement on the bolt looks off in the picture, but is perfectly centered.
Reach of 75 and angle of -7 also looks to be correct.
I tried to capture the rise, also 8mm rise looks fine for me.
Stiffness and ergonomics is fine.
Also if you are wondering: to get it painted is only 20$ extra
If you anything else, just let me know.
What I don‘t like: Top cap could be more precise (maybe because it is painted). Computer mount faces straight forward, a little tilt towards me would be better. Maybe I need to try the titanium mount.
For comparison: I also have a Vision Metron 5D evo on my roadbike.

How do you like it vs the Metron 5D Evo? I plan on switching to either that or this to replace my stem + bar combo that came w/ my Argon 18 Sum. Since the Sum has these 3D spacers, I figure the 8mm of rise would help me reduce how many spacers I'm running. The Metron is obviously more reputable & is on a pretty steep discount atm so wanted to hear your thoughts.

Debating between the Zeit Pro and the Blade for my next build. Can someone confirm the standover height for the Blade is actually that high? Stack and reach wise size S (486) is nearly identical to my SSE Gen 4 in size 48 (even a little more upright in fact), but factoring in the standover height (764mm) then it's a huge difference. Only size XS (456) is short enough for my standover height but it's a good 10-15mm lower and shorter than my SSE.

Reached out to Jack for inquiries about having a size 49 made but they don't have any molds for that. Unfortunate as I was debating between this and the SC-R55D...

I have this Romin Mirror copy from Ryet and it is the best saddle I've ever had.
Weight was about 183gram so not the lightest.

I bought another one for my MTB because it was so good, especially compared to other lexon/ryet saddles. I've tried 4 of their saddles, but this is in a different league. Carbon looks way cleaner, and overall  3d print is really good.

Has different hard spots and soft spots, so I'm pretty sure some thought has gone into this saddle.

Other saddle I've tried from ryet are: Premium 3d (Saddle rails were out of alignment, so got a warranty, which was also out of alignment lol.), Ultimate 3d carbon, Aircode carbon

Let me know if you need any more if or pics of the saddle

Oh wow I was looking into the Romin copy as well along w/ the Power Mirror copy. Did the decrease length (compared to the actual Romin) change anything for you? AFAIK, the Romin is more of a curved saddle instead of a flat one like the Power so I was thinking the extra length would help in climbing

It looks like Chinese saddles are quickly improving their 3D printed mesh process. I'd be curious to give these a try.

Going from left to right, looks like a Romin Mirror (15mm shorter), Fizik Vento Argo, & a variation of Power Mirror.

The Romin Mirror has the most reviews from another listing while the other 2 do not have as much. I'm curious to try this as well but might just get the Velobuild's version of the SMP Dynamic to try
