Here are the same hubs without logos and significantly cheaper I will find a drawing for geometry somewhere and post it later, I saved it, because it was under the listing.

Hey guys, I'm planning a wheel build with the
Kore Hubs 24t 270g ratched

https://a.aliexpress.com/_EQ4H1wO

hub and need the hub specs to calculate the spoke length. Does anyone have the PCD (Pitch Circle Diameter) and Center-to-Flange measurements for me? Thanks in advance!"

1. Is 25mm internal still the right direction for 2026 road use?
Yes, 25mm internal is perfect. It's now clearly established that 30mm tires are becoming the standard, and many riders are already using 32mm and even 34mm. So 25mm internal width aligns very well with where modern road setups are heading.
2. Is ~34mm max width ideal for modern 30mm tyre setups?
Yes, exactly. With wider tires becoming the norm, having an external rim width of 34–35mm will be important from an aerodynamic perspective. This supports the tire properly and optimizes airflow around a 30–32mm setup.

3. Would you prioritise lower weight or higher load/impact margin?
Weight — especially rotating mass — is always critical. If I were Zen, I would definitely aim for a wheelset under 1000g. From a marketing perspective alone, this would position you as a benchmark manufacturer at the cutting edge of development and production.
At the same time, as you are already doing, I would offer a reinforced version for heavier riders. That way you cover both performance-focused customers and those who prioritize durability.

4. 20/20 rear — acceptable for modern road builds?
Fewer spokes can also bring aerodynamic benefits. An 18-spoke option could even be interesting, simply because very few brands offer it — that could be a differentiator.
For me personally, it's only relevant if it delivers measurable aerodynamic gains without significantly compromising stiffness or durability.

5. Any concerns with U-shape profiles at this width and depth?
For 2026, rim shape is probably the most critical factor. It must handle crosswinds very well — this is where the real differences between brands become clear. Stability and predictable handling in wind are absolutely key.

Do you have a actual link, it seems that they are not avaiable any more?

Clone of Trek aero bottle and cage. $60ish/pair.

This is the problem I do net get an answer from the Reseller very frustrating.

I hope someone can help me. The ratchet rings on my rear wheel are damaged. Now I need replacements – does anyone have an idea? They don't seem to be original DT Swiss ones, judging by the thread pitch and diameter. Ideally, I'd like ones with about 36 teeth, because the steel 60T ones are far too delicate.
Thanks for the help – maybe someone can assist me.

The problem is that all upgrade kits have fine threads, but mine doesn't – and the screw thread is also larger at 35mm compared to DT Swiss EXP. A complete disaster.

Can someone help me for the right DT Swiss Freehub XDR Body for this hub? And should i also change some other parts on the rear hub like Bearings or the spring or the ratched system?

Would be great if someone can help me or has experience with this rear hub.

Perfect this is what I am searching, best would be to have some similar in an entry price level. But this is better than nothing :-)

Buzzer sound!  Incorrect answer!   Below is a link to what you need.  A Shimano spaced cassette that fits XDR!

Can anyone help me !!! I would need

a cassette for Shimano 12 speed Di2 but with XDR Freehub.

Original Sram Cassettes are not working really good.
Thanks

What are the lightest boost hubset that we can order from Aliexpress - is there something under 300g for both?

I am motivated to test something lightweight from Ali :-)

What ist the weight of the Medium Frame?
