This is my third post on a persistent problem I'm having. To summarize:
Post 1: Couldn't tighten headset fully. Turned out the steerer nut was too high or had slipped up to
the top cap. Fixed by LBS. Post 2: I thought the steerer nut (which I called a star-fangled nut) was
still slipping in the carbon steerer. Turns out (as many people noted) it's actually a wedge-type
nut, and in fact it hadn't slipped.
Here's the problem - when I do the normal loose-headset test (hold the front brake and rock the bike
forwards and backwards), there's a knocking sound. Sounds just like if the headset is loose and the
steerer is moving within the headset/headtube. Can't tell exactly where it's coming from except that
it's along the fork, somewhere between the hub and stem.
The LBS insists the headset is properly tight, and as far as I can tell it is. There's no movement
between the adjustable race and the upper head-tube race when I put my finger where they meet while
rocking the bike. Same on the bottom part of the headset.
The LBS couldn't figure out the source of the knock, and gave up. Any ideas?
Specs: new Litespeed Tuscany ti frame, Cane Creek S2 headset, Litespeed carbon disc & canti fork
with carbon steerer, Avid mechanical disc brakes, Hope XC disc hubs.
Thanks, Michael
