My experience as a mechanic for riders who put a lot of miles on their bicycles has shown me that Campi equipment lasts up to 4 times longer than other equipment. The best thing about Campi components is that they are of such quality that they are far easier to rebuild than a lot of other products that seem to be expendable. You are probably not to familiar with them because FiR, like a lot of Euro bicycle manufacturers, are under promoted in the United States. When you see more real-life photos than promotional advertising it's a good sign. Pro teams often ride what they get for free, as part of their sponsorship, not necessarily reflecting the quality of the product.
FiR is a small, independent Italian company that only makes bicycle rims.
My hope is that they will not be bought out as so many smaller companies have been, and then possibly, in the interest of volume, be forced to drop their classic and more technically interesting rims - touring, and box section for instance. As a wheelbuilder, I have been using FiR rims with great success for about 15 years. FiR's quality is exceptionally high. I find that I can achieve a round wheel using nearly even spoke tension all around the circumference. That simply means that the rim was nearly round to begin with.
