Notes from MyBikeThing
This is the single most useful $20 part in vintage road conversions. Old frame, downtube bosses, and you want brifters or bar-cons — these bolt straight onto the existing bosses and give you proper housing stops with barrel adjusters right where you can reach them.

Grease everything before these go on
