I'm just guessing here, but I think the more 'in-tune' your FD/RD are the less likely this is to happen. I remember this happening to me in the past, but not since I started working on my own bike and getting everything really dialed in. So it might just be correlation that it doesn't happen anymore (since I probably soft pedal a bit and don't think about it) or it might be causation (because my drivetrain is better tuned now).
A suggestion that might help, increase b-tension on your RD. I might be totally wrong though, so take with a couple grains of salt.
Yeah, I'm sure it doesn't actually hit the chain stay but it seems like it...it gets pulled that direction as far as it can go. I'll give the b-tension a shot. I haven't messed with that at all since I built my Felt so who knows, maybe that'll help. Other than this little issue, the bike shifts perfectly so I'm not really that worried about it, was mostly curious if others had run into this. Thanks for the suggestion.
