NOS (New-Old Stock) Dia-Compe brake spring for Gran Compe 400.
Dia-Compe part number: GC46.400 (see diagram in 2nd photo)
Size: The width at the widest point is about 80mm. The "height" is about 35mm (uncompressed)
These came in a shop bag of 10, so they are definitely GC46.400. They are shiny chrome and pristine. You will receive sealed in a plain plastic bag. They may fit other brakes, but the only diagram I can find that shows this part number is for the Gran Compe 400.
THERE ARE NO RETURNS ACCEPTED ON NOS (NEW-OLD STOCK) ITEMS. PLEASE REVIEW THE PHOTO, THE ABOVE DESCRIPTION, AND ASK ALL QUESTIONS (at email@example.com) BEFORE PURCHASING.
