I have been given a Pinarello FP3 by a friend (who now rides for UKyouth and Cervelo). He hardly rode it but did have a slow tangle and pulled out one of the STI cable stops(and lost it) held in by two rivets. Anyways hes given me the frame and forks but I need to find the replacement part. I've contacted Pinarello direct but nothing from them yet(been a while). Any ideas where I could track down such a part?
