Personally I'd take a punt at that price.
Lets face it, plenty of us on here reguarly ride ancient aluminium and carbon frames and components that are probably well past their Use By date... 25 year old alloy handlebars anyone?
This is probably less likely to fail than many retro-components.
Yes, similar to my line of thinking.
In the end bottled it and went for a 1/2 price Easton EA50 from Wiggle
. Mostly because I wanted something asap, partially because it was cheaper, partially because it's to go on the winter bike which will be sh*tted up in no time and slightly due to that nagging doubt...
