bystander Wrote:Freccia valves were widely available as an aftermarket replacement (distributed I think by Causeway Autos/ Northwoods, and sold by the various A7 specialists) around 40 or 50 years ago, but have not been around as far as I know since then. There was nothing special about them, they were not oversize, and any standard A7 valve will do to replace them.
Older than that! I was introduced to Freccia valves by the late Ray Stevens (anyone remember him?) in the late 1970's and they were obsolete then!
There was something special about them, they didn't burn out like the then commonly available new valves, on leaded petrol.
I still look out for them although the new valves sold these days seem to be much better or perhaps the lack of lead helps. Or is it that I'm not doing 20,000 a year any more??
