I did not know FiR made components, but I have a set of FiR Zenith clincher rims that are very nice. From around 2000-2001. They were sold to me as comparable to Mavic Open Pro rims but nicer. Some people complained of noise from Open Pros around that time. They have double eyelets too, which you don't see much anymore. If you want FiR rims, they have less that 500 miles on them. I moved the hubs to a wider rim since the Zenith are 13mm inside.

Red Rose Imports may have been the importer of FiR back around 2000-2001. I bought a Coppi bike with Campy Daytona components and the FiR Zenith rims. It was whatever was the one year Campy used Daytona before they had to change it to Centaur.

Here is Red Rose Imports website. May be worth an email to see if they know.
