A little the worse for wear but still 100% serviceable...

The Delta - later the A9 - is a superb headset with enormous load capacity and smooth feel due to the fabulous needle roller bearing races. This run against hardened steel collars inside alloy cups. All sealed with o-rings. Lighter than sealed units, last longer and can always be cleaned down and regreased at will.

All.parts present and correct. I have one of these on a Tony Oliver Tandem dating back to 1987!
