I own a Cannondale Super Six 105 (Ultegra now) Carbon 2012 bike and I can't stop the wobble in the headset. If I tighten down the top cap (with 6mm hex) I can get rid of the wobble (hands on the drops holding brakes - headset has a fair bit of play) but I cannot move the wheels freely with the handlebars.
I stripped it down, cleaned it and assembled it again but its still wobbly after tightening the inner 5mm allen key.
Do I need a new headset ? It's KP044 I think.
The bearings move around nice and easy but the compression ring feels very rough to touch.
The bike is 4 years old, 30,000+km cycled on it, I'm not sure whats wrong -
(1) I didn't tighten properly (2) headset needs replacement or (3) bike is old and something wrong with frame.
Would a new KP044 fix it for me or could the bike be kaput ? Also if I cycle on (1-2 weeks) with a wobble will it do damage to the frame ?
I don't know if the pictures are much of a help but everything is there except a bit of a rough corner feel.
