I received such a frame from a friend of mine. One of the aluminium BB inserts de-bonded from the frame and since he wasn't too happy about the stiffness of the frame either, he decided not to use it anymore. I could do whatever I wanted with it (I build and repair carbon parts on an amateur level). So I cut it in half.

I will post some pictures later, but a few comments first:
The frame was incredibly light, 728g for a size 54 to be exact (no typo). Since I highly doubt that HM fibers are used in such a frame, I suspect that they simply reduced the amount of stiffness layers to achieve such a low weight. Or some precut pieces fell to the floor and the person laminating the frame decided not to use them anymore That's also in line with the owner's feedback who said the bike felt pretty noodly.

The good: The frame is surprisingly well built, the inside in general looks very clean. No wrinkles and almost no voids.

The bad: The rear dropout for the derailleur hanger I find horrible, it is so thin. This was mentioned in this thread already. The connection where front and rear triangle is glued together is done poorly too. You'll see why on the pics. The integration of the seatpost shape in the seattube isn't a showpiece either (an OEM SL7 seatpost doesn't fit, BTW). The BB area is pretty thin compared to other frames that I cut and honestly, I'm not surprised that one insert decided to part ways.

Would I recommend buying such a frame from a manufacturing/engineering perspective? Absolutely not. I'm not squeamish when it comes to carbon parts but IMHO I'd stay clear from such a frame.

Guys, did you order those wide wheels for the road bike?
Is 34.18 too much for a road bike.
I'm thinking about this wide option but I'm worried about the frame (winspace t1550 2gen). Will it fit the frame. I haven't frame yet so I can not measure it.

The carbon is 25 mm thick. According to SRAM you need 5-7 mm for the brakes (so 30-32 mm in total). I use 32 mm for the Red Caliper.
