Not recently, but yes. I've had these rims since the mid-80s. Hot summer day in the hills. Guess I was riding the brakes too hard. I rolled the rear tire and flattened out the edge of the rim sliding across the pavement with the rear locked up.
I was debating bringing these rims out of retirement if they check out as round. Though they are tad on the heavy side at ~850g for the pair (with glue residue and some tape). It was so long ago I just can't recall how bad they were when I retired them. I don't lik the idea of spending time/$ building wheels that will never stay true. I don't know, what do you think, everything else notwithstanding, would you build rims with this sort of damage? The rims are kind of cool and I like the breaking surface, esp. on ano'd rims is a plus. I bought these as a teenager in France, so they also have some nostalgic attachment. How bad could sudden wheel failure be? Don't answer that.
