Thought i would post this as i have never had a rim go bang on me before.... I have had them for just under 3 years and used them quite a lot. I knew that the rim was worn as i could feel it, but there are no indicators on it so couldn't really tell how worn. Luckily i had just descended and was on the flat when it literally exploded, so i managed to come to a controlled stop. My cycling buddy thought he had been shot it was so loud!!
Any how, its worth checking your rims out and if in doubt get your LBS to have a look, if it had been the front or on a decent then it would have been nasty....
I also think those Swissstop green pads wore it quite quick!!??
FYI people - look for cupping of the brake track. If it gets significant than it's time for new rims.

Have a pair of a similar vintage that were retired onto the winter bike, and the rims are starting to look rather worn too - they have a fairly obvious concave now. I've have been meaning to sort them for a while now...but i think it might be replacing them sooner rather than later having seen that!
Pretty sure you can order new rims from campag and rebuild them, assuming the spokes and hubs are still good.
The fronts are very very similar, in my opinion the rears will get more wear..... and I guess they will be the first to go though - Its difficult without wear indicators just how much 'cupping' you risk?!
Yep these were on my winter steed. I did order some new wheels the week before they went pop and i was due to have them but they sent the wrong hub so they were delayed a week, its a bit ironic how it was their last ride when they went bang!!
I did look into replacing the rims but was quoted £368.22 just for the rear rim/spokes and rebuild!! So bought some new hand built wheels instead!
I will try and take a photo of the rim tomorrow and post up!
And yes if yours are bad then bin them!
I've come to the same conclusion. I think these pads on this rim is a terrible combination, but it's taken me all of four years of poor braking and horrible grinding sounds to it work out. (I'm a slow learner.)Lig wrote:I also think those Swissstop green pads wore it quite quick!!??

Then Stan's Alpha340 rim is ready to blow even when new. I cut one up and measured the wall thickness of the rim and brake surface. The brake surface was .9mm and the wall thickness was .5-.7mm, the thickest section was the spoke bed at 1.1mm thick.
BTW you could get a set of Zondas for the price of that rim and have £100 to spend on something else.

UK roads get very greasy in autumn and winter. It makes sense to use the rear as well as the front as it's easier to control a rear wheel skid.
