There have been some design problems in the past that have resulted in recalls like the Modolo stems about 15 years ago but generally speaking vintage parts properly maintained are being ridden 60 years or more after they were made.
This quote from my new Winwood user manual does not sound like simple lawyer speak: "High-end bicycle components have a maximum life expectancy. A professional bicycle mechanic should regularly inspect all bicycle components, especially steering components. At a minimum, a regularly used handlebar or stem should be replaced every two years."
When does it become my fault for buying something like this? (not that I knew the limitation before the purchase)
Especially in light of the fact that my 25 year old stems and handlebars still work fine.
