I have a 2006 Giant TCR C1 full carbon road bike with Dura Ace rear and Ultegra front.
It has been dropping the chain off the front rings a bit lately and I had the LBS install a new chain.
It still is dropping off the front occasionally and this is really getting me aggravated as it never used to drop chain.
I want to change up to Dura Ace front but I'm unsure of which one to buy. There are many Dura Ace part nos. for front Dérailleurs on eBay.
