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.

I will find a drawing for geometry somewhere and post it later, I saved it, because it was under the listing.
