This is a vintage Mavic Open Pro rear wheel - 700c / 622x15 size - with a used blue/black Michelin Pro 4 23mm tyre. Clincher type wheel.
It has a skewer and takes a freewheel.
Looks to spin fine, but may need new grease and/or bearings as it has been stored.
Happy to post, or can be collected from Dewsbury, West Yorkshire, WF12.
