Hopefully Berk won't mind me reposting, but when I got one for my R5ca he asked me the following:
1) saddle shell shape (I can make a few saddle shapes that are based on Selle Italia SLR, Tune Speedneedle, AX Lightness Sprint, Fizik Antares), and of course my own saddle shape (with the groove/cutout)

2) seatpost lenght (from the top of the saddle till the end of the
seatpost - min. insert is around 70mm) usually it's better to make it even a bit longer just to make sure in case that you would like to adjust it

3) seatpost diameter (27.2 or 31.6mm) or stubby (like Trek Madone etc.) or an original seatpost (if it's an aero profile)

4) setback
(the distance measured level with the saddle shell from the
saddle nose till the start of the seatpost - where it should meet when
it's integrated, see distance "X"), you can also photograph your
curent setup and just put a ruler on the top of the saddle and
photograph it from the profile from at least 1m (to avoid any optical
illusions), and then I can take the measurment based on the photo

5) seatpost angle (if you prefer to have your saddle level then I only
need to know your frame geometry)

6) beauty look of the combo (plain, twill or UD look, it can be also
mixed, for example UD seatpost with plain saddle etc.,..)

7) matte or gloss finish (it can be also mixed) and graphics/stickers (without them, or with black, white, etc.,..)
Prior to ordering mine, I was apprehensive about the comfort of it. With the padded version I found it comfortable as there was a decent amount of give on the wings.

Will riding an integrated seatpost/Lupina saddle feel the same as a non-integrated seatpost and Lupina? As I recall, the saddle to seatpost attachment with your integrated set-up is different (uses a single, center rail attachment).
I had my bikefitter give me details of the tilt, fore/aft measurement and length needed for the saddle/post combo. It will definitely feel stiffer and you'll get more road feedback because it gives a more direct connection to the frame.

Hi, thanks for all the kind words!!

Regarding the Lupina model - it really isn't as flat as a Toupe, hard to compare all those saddles, they really look similar, but it is hard to comment until you try it. We are working on new saddle models, we'll keep all the saddles as we already produce them, and with the new one we will start most probably already in April, the moulds are already in production and I'll update you as soon as we have a few saddles finished. We tested different prototypes, and came up with that design, this is how we imagine shorter and wider saddles - for sure something to consider for all those who prefer wider saddle nose. The properties of the saddle still remain quite similar to our Lupina, there is the same technology and know-how in that saddle shell, only a bit different shape. I'll post some photos most probably in the next few days, will give my best to update you as soon as possible!

Thanks for the repost! The integrated saddle is really something different, it isn't as comfortable as a standard railed saddle, but if you are sure in a certain saddle shape then it is no problem at all, but the feeling is really a bit more "direct", similar like riding with a flat tire :-)

Thanks for making these great saddles, I just got a Lupina padded and it's awesome, the saddle disappears and you don't notice it.
The other saddle I am using is the Specialized Romin Evo which was also great but was looking to save some weight. Seems like these 2 saddles are similar in shape/characteristics although the Lupina has more width and longer rails which is nice as you can adjust it better.

I've been using an unpadded Lupina saddle for almost 5000 km in less than 3 months. Has to be the most comfy saddle I've had, except the first gen toupé saddles from years and years ago.

I don't know if I ran into issues, but, as you can see from the pics of one side of the saddle (really hard to capture on camera), and the same happens on the other side, but there seems to be cracks on the exact place where the support from the rail underneath the saddle stops. I'm only 71 kg, saddle with oval rails is rated to 90 or more. And only road use, no mtb or gravel.

Not easy to see, but I can also feel the 'cracks' with my figer nail. How do I know if it's only clearcoat of structural. I don't have any weird noices and the saddle still feels the same as when new. I don't really have a spare saddle for the moment, so sending the saddle back (bought via R2-bike) and waiting for verdict is not really an option. What do you think?

I think you should contact Berk instead of posting on a forum

Will do, but, berk saddles are very popular here on WW. I was wondering if I was the only with such 'issue'. We are here to share experiences, so, for me, nothing wrong with my post :wink:

Can someone advise on saddle width on the Berk saddles? Would like to try the Lupina, and have sitbone width (according to Meld) of 124mm. Which to go for?

Way cool to see Berk on GCN!

...and for the record, my Berk Lupina (7x9 rails, 132mm wide and UD matte) is on its second season with no visual or audible ugliness.

My only sadness is having to live with a plain black carbon support at the tail end of my Lupina. No custom painting for me. Poor me.

Just received my new Lukna yesterday. My previous Lukna was a matte look one as well but that had a smooth texture while this had quite a rough feel to it. Anyone had a rough matte finish to their saddle as well? Am wondering if it'll wear out my bibs... Image

Hi to all!
Sure, no problem to share anything, we will always give our best to respond as soon as possible, and if there is any problem (you know, sh#t happens) we'll make sure to take care. So if you have any questions, doubts etc. just drop us an email.

For the matte finish - usually a brand new matte part has a bit more rough finish, and it gets a bit polished after some use.

Otherwise our weightweenies project bike is now at 4,24kg:
