Missing screw -DuraAce Front Derailleur cage
I've been experiencing lackluster shifting problems up front on my bike of late. While riding, occassionally my chain would hesitate moving to the larger chainring.
Upon closer inspection, I discovered that the screw at the bottom of the cage had fallen out. Therefore the bottoms of the derailleur cage would permit flex and therefore shifted erractically.
I looked in my parts bin and my other Ultegra and 105 front derailleur cages have a different design. The back plates on these cages are threaded only requiring a single screw. But the DuraAce cage just has a large hole in both sides of the cage. So I cannot cannibalize the small part from my parts bins.
I would assume a short screw and a bolt/washer on the other side is appropriate.
Is this obtainable? Or should I just go to the local hardware store and find an inexpensive screw/bolt combination?
