What the third saddle back from the front? Is that the hlod? It's the most Aliante-esque looking profile I've seen from your saddle line.

I am in awe of how far your product line has evolved, those wheels must be incredibly difficult to produce. I run tubulars myself but know many friends who would jump at the opportunity to acquire clinchers in carbon monocoque. Great job Berk and keep them coming!

Hi, thanks to all!!

Yes that is a Hlod saddle.

For the wheels - we are working on it, also clincher hopefully in the future, but still a lot to do. But the progress goes nice.
We are waiting for our partner to produce a special prepreg that is made on our request. It may take a few more weeks or even months that we get it, and then we can continue with various tests..

Some more custom work, to complete the front brake fairing we posted previously (for that Bianchi)

503g for the finished setup, almost half the weight of the original setup

You really need to do an aero bar setup....you would sell a ton! What incredible work.

I just ordered the padded Lupina one hour ago.

I have been reading this thread and got an idea.
We Trek users REALLY need a better seatpost (seatmast) than what is offered by Trek.
With a different clamping system !
And LIGHTER
The Trek "ride tuned seatmast cap" is a reverse install from a regular post.
The bike frame has the post, and the seat mast slides over the post like a sleeve.
The Trek/Bontrager saddle adjustment is from Hell.
We need a seatmast compatible with Trek frames with a two-bolt adjustment.
Your seat clamp shown earlier would work great .
I don't think this would infringe on any patents since you would be using a different mast top and clamp.
The only common idea is that it is an external sleeve mast, rather than an internal post.
And ..... there are thousands of Trek riders - which would justify the product development cost.
Thanks and keep up the good work.
Dan

I had a Boone disc, I had a ceetec post , other planet compared to stock one

Hi,
thanks for the compliments!
The weight depends from the specifications, but for a disc frame it is usually around 850-900g for the frame.

Otherwise we are experimenting with new materials, and we made an interesting prototype. The complete frame, with derailleur hanger, integrated seatpost and saddle is only 643g painted! True weightweenies:

The complete set as on photo - frame, fork, headset, integrated seatpost/saddle and handlebar are 1209g:

I already did a similar frame years ago, those who follow for years will remember that bike, here just a photo with the same wheels as I used for that build years ago:

This one is from 2011:

On a bike ride with my friend Luka Pibernik, who was my team-mate in 2011, I used to ride that bike quite a lot, nice memories :)

:shock: :shock: :shock: Quick comparison shows this way you can save at least 250g from other uberlight builds :shock:

Finally just ordered Berk Lupina. Having followed progress on here for years I'm looking forward to it arriving in the UK.

If it fits me and is comfortable I will be in touch to order another custom one for another bike. :thumbup:

Hope you enjoy yours as much as I do! I did back-to-back 100 mile rides this past weekend with my Berk (unpadded, 132mm) Lupina. No issues at all. :)

Please put on your new wheels on that frame as well and tell us how it weighs!
