Hi, up for grabs is a NOS Maillard Helicomatic freewheel from the 1980's.These fit ONLY Maillard Helicomatic hubs with the built-in helical splines. This will NOT fit any other kind of hub.If you're reading this, it's probably because you have a pair of wheels that need this freewheel!This 1 is 6-speed, 13-15-18-21-25-30. Brand new, never used, in its original packing grease.Please see my other items for a 13-32 6-speed.
