There are many real weights in the Bora topic on this forum. The 35's have a more neutral and unnoticeable feel, whereas the 50's are more noisy. That is something you either like or not like... The pre-2015 Ultra Twos were not as good in crosswind as the new 50's. I have ridden both back to back and do not regret buying the 35's.

No weight difference? That can't be right...

There's a 55g difference between the two listed weights, can you feel that on the hills?

With the Ultras... you're paying for the CULT bearings/races, not weight reduction.

Official weight on Ultras are lower then One.So their marketeting is that u pay for better bearings and lower weight in Ultra.
Anyway good to know that One are a bit lighter then Ultra

Real weight on a calibrated scale for Bora One 50 and Bora One 35 tubulars (fresh from box with no glue applied):

Bora One 35 front; 495 gm
Bora One 35 rear: 690 gm
Total:1185 gm

Bora One 50 front; 525 gm
Bora One 50 rear: 685 gm
Total:1210 gm

...difference of only 25gm between 50s and 35s

Skewers on both wheels sets are identical weight:
Record Skewer front: 55 gm
Record Skewer rear: 60 gm

As far as difference in road feel IME...the 50s catch a bit more cross wind, but nominally. Also, the 50s are a bit less forgiving, vertically, where I feel a bit more of the road, but laterally they feel identical to the 35s, very stiff with a direct response when you put power down. They both climb like u r riding a hot air ballon. I run Vitt Pave 25c on both at 90 psi rear and 85 psi frt. The only advantage with the CULT bearings is the longevity of the bearings over the lifetime of the wheels (the CULT stuff when serviced regularly will last forever)....anyone who claims they can FEEL the difference of CULT bearings (compared to the hybrid ceramic USB bearings), is full of it. As others have suggested before, you can ALMOST buy a pair of Bora One 35 and 50 for the price of one pair of Ultras....albeit, I will admit that aesthetically the carbon hub shells on the 50s are bling.

Tubular standard
35 - 1170g
50 - 1215 g
I don't feel much difference in weight,
I feel that the speed that I feel on the hill is not going to be a little bit steep,
This is not a big deal.
However, it is clear that both are good wheels!

I am also looking at a Bora wheelset and I look it like this:
- Crosswinds, then Bora 35
- No Crosswinds, then Bora 50
- Only climbing, then Bora 35 (but Bora 50 also ok)
- Only flat, then Bora 50 (but Bora 35 also ok)

35 is the uphill hill unconditionally favorable?
If I were to choose a visual effect,
