IRD 5-speed "HG" 13-28 freewheel. New, $60.00/each

Part# 55125

• This freewheel is 29mm wide
• We added "HG" to the listing because this freewheel has Hyperglide-type shifting ramps.

Here's the box. It looks like we are the second shop to own this freewheel. We assume this was returned to the distributor by Harris Cyclery, a much-revered bike shop in Massachusetts that recently closed after a 70-year run.
