They of course were made by PARK now just in the bike
tool business but originally quite a high volume SCHWINN dealer
made them for SCHWINN under private label and everyone else under "PARK" real cool ones were alloy with plasic covering.
I still have an alloy Handlebar bag support in the garage its primary use is holding the TA bag on my ALEX MOULTON.
enough name dropping for the day
had a nice ride today on a bike that has been talked about to much recently
