Before I dig into it and start taking things apart thought I'd query ST. 5 or 6 year old QR Kilo that I just noticed is loose at junction of the seat stay and dropout. It appears to be a "two part" system with the traditional horizontal dropout then another metal component that bridges/forms the seatstay/chainstay junction. The top flush mount screw seems to be very tight on an initial half hearted attempt at loosening/tightening. The "play" seems to be around that screw like maybe the metal has worn away from the screw head. Anyway, before I get real committed at taking this screw/plate/dropout system apart and seeing if it is a metal wear issue, carbon crack, or other problem, thought I'd see if anyone else has had this happen and what they found/did/etc.



I am referring to the seat stay junction/top screw which is flush mount, the other two drop out screws seem firm/no play/no play at chainstay. I messaged QR yesterday re. this and have not yet heard back. Work time permitting will call today as well.
