Dia-Compe Cable Housing Clips
These stainless steel clips are for securing housing to frames without brazed-on guides. Perfect for restorations and are available in all three common steel tubing sizes - 25.4, 28.6, and 31.8mm.
Sold in packs of three.
Very close match to the original cable housing clips for my vintage 72 Fuji Finest, which had gotten badly pitted and corroded.
