Glad to hear these are being fixed under warranty. For how long?

Are the tubes round? Perhaps one could replace the bracket with a clamp.

That looks like a lot of rust on that derailleur for a 2 year old bike.

I've got rust everywhere else on my bike, but my Campy FD is about 45 years old with less rust on it than that.

That Shimano Ultegra derailleur is around 5 years old. I moved everything from my old bike to the Evo. I was a noob back then and didnt take care of my gear.

Ok, a couple of extra years and a different bike makes sense.

Is this an Ultegra issue? Looking at my bike, with years of commuting, riding it in the sun, rain, and even snow, anything that can rust, has rusted. One of the major exceptions is no rust on the Campy sheetmetal parts (FD, cable guides, etc), even where the FD has rubbed the chain (with oil, of course).

What is the cost difference between making a derailleur cage from stainless vs chromed steel? It can't be more than $1. Probably a lot less. I did check, mine do attract magnets, but some grades of stainless do.
