I’ve had this change in mind for a long time. The blackcatwheels.ch blog was created many years ago and, in reality, it was never a true online store in the full sense of the word.
CarbonOne.pl, on the other hand, was initially meant to serve only one specific project – wheelsets built with carbon spokes. However, it felt like a waste to use a fully developed e-commerce system for such a limited range of products.
After giving it some thought, the decision was made, and now you can find my complete portfolio here in one place.
CarbonOne wheels remain in the same place
CarbonOne wheelsets are still available in the “Road Wheels” and “Gravel Wheels” categories.

Custom projects — now in one place
Individual builds can now be found under the “Custom Wheels” section.
I will be gradually adding completed projects there. This is my response to the many questions you’ve asked about examples of my work.
Each build will include a short description, key characteristics, weight, and pricing. I hope this will give you inspiration and help you imagine what your own future wheelset could look like.

Components: rims, hubs, and spokes
In the “Rims, Hubs, Spokes” section, you’ll find most of the components I use in my builds.
Use the subcategories “Road”, “Gravel”, and “MTB” to filter products more easily.
As for brands, you’ll find both my own BC-labelled components, as well as Duke, MCFK, Schmolke, Bitex, Acros, CarbonTi, DT Swiss, Erase, Extralite, NonPlus, Industry9, Onyx, Tune, and many more.

All components include up-to-date stock information.
Items in stock are shipped almost immediately. Other products are available on request, with an average lead time of around 5 business days.
I offer a very broad spoke assortment, especially Sapim. Spokes are cut using Cyclus and Kowa rolling machines in 1 mm increments, so you can confidently order odd lengths without any problem.
On request, I also import BERD spokes and carbon spokes.
Service and tools
Everything related to service can be found in the “Tools & Service” section.
You’ll also find details about my wheelbuilding training sessions, as well as professional tools such as tensiometers, spoke rolling machines, and calibration equipment.

Don’t miss the Clearance section
Be sure to check out the “Sale” category — you can find truly great deals on hubs, rims, and even complete wheelsets.
