Nova Superlight Oversize 46.4mm Head tube and Reinforcing Rings
The Superlight Headtube is 220mm long with a 1.25mm wall. the I.D. is 43.9mm- perfect for press fit after light reaming. Normally this will require precision reaming after building the frame to get perfect roundness on the I.D. King and Cane Creek headsets require a slight interference fit.
The rings can be brazed, silver soldered or TIG welded on each end of headtube for reinforcement of headtube cups.
A nice enhancement for the 46.4mm headtube - please see: Item #201977-3600
