Hard to say where it gets in. If it were the cable guide (or anywhere on the bottom-side of the frame), I'd expect it to leak out too. The most likely "openings" on the top side would be the headset.... But that seemed unlikely....
I'm curious if other owners of Raleigh's 2007 RC7000 carbon have had trouble with water getting *inside* the frame. When I ride in wet weather, water somehow gets in, but I'm not sure how. I'd appreciate any insight others may have. Thanks, Ron
