Lugged carbon frame... Is it safe?

Ive got the same frame. - purple / blue. (trying to put a year on it.)
Run fine for year and a half.

Had the same question about an dynatech 725ti because of the glued tubes but thats running fine fixed too.

here you go, looks like mine is actually a 92, half the components havebeen upgraded over the years, carbon forks going on it soon. Would like to get the paint off and polish up the aluminium one day like this guy has done. Looks sweet but a fucking mission.

Are you still running it with the sti levers? I had big issues with mine until I stuck in a load of GT40 and some lube and it was as god as new.
