They either have less rolling resistance or more comfort, not both at the same time.

And in my experience, albeit clouded by frame material etc, the road comfort going from even a 28c road bike to a 42c gravel bike is marginal. We're still talking about zero suspension frames and bumps being handled by a few mm of tire. Narrower tires are lighter and more aero. I think for decent roads 28c is the sweet spot. 32c makes sense more for flat insurance than comfort IMO. I have 28c and 32c on some of my bikes and don't feel a huge comfort difference.

The link you showed clearly states that the rolling resistance goes down as tire size goes up, and we know that wide tires are more comfortable because you can run lower pressures and have the same air volume in the tire. Whether you feel that difference is up to you, but the physics doesn't lie. Wider tires have less rolling resistance and are more comfortable.

Now, it's possible that after a certain size we start losing speed again, but 32s aren't that size (NorCal Cycling tested 28, 32 and 34 and found that the 34s were slightly slower than 32s, they were on par with 28s, with the 32s being the fastest ).

Hello everyone,
are there any more buyers here in the forum who can share their experiences?
I am interested in the bike as a cost-effective alternative and am thinking about placing an order.
Some good photos in daylight would also be nice.
What weaknesses have you identified? I would be happy to receive some more information...

BikeVibes just recently released their 6 month review video, here is the link in case you missed it.

Are carbon spokes worth it? I'm worried they ride harsh and are more difficult to tension due to less stretching nature of the material. Looks and weight are great - price also justifiable. But are they actually better as for ride quality, serviceability and longevity?

Carbon spokes are only really better for weight and maaaybe a bit of aero, but they will in general ride harsher, harder to service, easier to break (I've seen carbon spokes break when the rider in front kicked up a loose pebble into the wheel of the rider behind). They will feel stiffer but it's up to you to decide if you want or like that. In my opinion, if Pogačar can win every race under the sun with steel spokes, I believe you can too.

High stack, short reach, more aggressive geometry than Factor but less than Pina X

I might be reading this wrong but I assume you meant less aggressive geometry than Factor Ostro but more aggressive than Pinarello X, unless I am unaware of some super relaxed Factor.

Here is my only question now: which position do you like the battery located ? Seat post or low side of bottom bracket ?

If you stick to T47 or some other threaded standard (which I hope you do, I hate pressfit) my vote is around the bottom bracket 10/10 times, especially if you manage to package it similarly to the current gen supersix evo.

Also, would it be possible to print a grid on the handlebars, where the levers are fixed? I often see horizontal lines printed which are great for setting the height, but people often angle their hoods in and having the grid would allow us to set both the height and the angle symmetrically.

Looks like the Workswell WCB-R-306:

I think you are right, the geometry charts line up and they visually look identical too

Looks good! Does anyone have experience with these Adapt bikes? How much do frames usually run for?
Edited: I found a thread from February after Eurobike in which someone says they're OEM only and don't sell directly to consumers. Too bad; these frames check a lot of boxes!

I guess the good news for you is that you can pick up a Hygge Model S and have that exact frame

Looks an awful lot like a Hygge Model S...

Is it 38mm? They say 32 on their website

Here is the picture he sent me when I asked him about it
