I had a set of Rigida Chrina rims on Tiagra hubs (32 f & 36 r), from SPA, last May. Front is still ok but the rear hub flange broke apart, quite literally on a commute months ago. I have since butchered the fubar'd wheel for spare spokes and nipples
Previously to this, a spoke went within the first 3 or 4 months (I was able to add tention to the adjacent spokes on-the-fly, and it took me about another 60 miles, remaining fairly true, that day). It was predictably followed by another, a week or so later.
SPA had a backlog or orders when I got mine and took about 2 weeks to build and ship them. They seemed nice enough when I phoned them to chase, if a little disorganised.
Being a heavy rider, you are going to break spokes on the rear. I learned to live with this and even though I am slightly lighter these days, I still break rear spokes and have wheels going out of true. Currently on a set of Planet X A57 32h cyclocross wheels, for day to day use and they have been ok for the first cpl of weeks I have used them, in anger. Bust a spoke 2 weeks ago on an Aksium and have since replaced it but not sure if I'm confident to do a long ride on them yet. They are waiting in the wings, as substitutes ATM. I am expecting problems with the Easton EA30s on my new Cube and they will likely go on there soonish!
It seems to be a neverending war, against broken spokes and meanwhile my collection of front wheels continues to grow, bah!
