Sounds like a guy building wheels who is living in 5 years ago technology. Carbon clinchers are proven good technology and most have 220-250 lb weight limit.

Psimet needs to catch up with the times they are changing.

I have 8000 miles of great experience and there are many others that have much more experience.

The wheel building industry has established that carbon clinchers are proven technology for this type of application and this little wheel builder needs to catch up with current technology that is proven and get informed.
