Headset Question

I have a Masi Evoluzione with a Ritchey Pro Zero tapered headset. About a year ago I was ran off the road and went over the bars. Got my wits about me and checked things out and all I could see was that the front wheel was a little crooked from hitting the tree root. I got that fixed and everything has been good with the bike up until about a week ago when I noticed some sloppiness fore and aft on the handlebars and headset. I took the assembly apart and found that both bearing cups internal to the bike frame were damaged and loose. I am planning on replacing the headset, and I am having problems finding those cups that the bearing sit in. They popped right out of the frame and look to have been epoxyed in. Does anyone know where I can find those parts?

Would be useful to know which model / year your Evoluzione is, as the Masi website has 6 models listed for 2013, all with different specs, without searching for previous years models.

As you haven't given the year, will take it has the same frame spec as the current models, if the headtube has ovalized. This is on the basis that it's similar in spec, although saying it has cups, it could be a ZS headset, more info from you needed.

Would be surprised if this had anything to do with the crash a year ago, as it's something that seems to happen to carbon frames with integrated bearing cups.

Its a 2012 Evoluzione with the SRAM Apex Group. I think it is a ZS headset. The cups appear to be recessed into the frame when I took them out.

Looks as though the went integrated for 2013, even so, as you have a ZS headset, the bearing cups still shouldn't fall out, having recently installed one, it takes as much pressure (using a Park HHP-2) as for a normal EC headset.

Would have a LBS investigate, preferably the one when you got the bike from, as being as it's a 2012, if there is an issue with the headtube, it should be covered be warranty (would avoid mentioning the crash last year)
