Sorry to subject y'all to yet another headset question I am a very experienced rider and usually maintain all of my bikes. But I really can't determine if my favorite roadbike headset has a problem.
2007 Specialized Roubaix Elite with about 6000 miles on the headset
I can't hear any headset noise but I do feel a very slight (really slight!) clunk when I lock the front brake and try to roll the frame forward- backward.
When I lock the front brake and hold my hand around the head tube I can feel a tiny movement (~1mm or less ??) movement between the head tube/frame and what Specialized calls the "headset cap."
I can find no torque specs for tightening the cap bolt (8mm allen) but I've tried every thing from slightly tight to tight enough to creak to "I really don't wnat to put more torque into this thing." The amount of movement when rocking the bike with locked brake does not change.
The bike handles well - descending at 35 mph in corners feels solid and there is no head shake, frame shake, speed wobble, or other evil sensations. The handlebars turn freely with no drag or catches. The steering feels very precise at all speeds.
When braking with just the front brake (just testing!) at low speed - MAYBE I can feel a little shutter in the headset.
I've read a bunch of other posts about the Roubaix headset (Specialized Mindset?). Many other owners have reported creaking problems with their Mindset headset.
Do I have a problem or am I just making up a problem?
I bought the bike "NEW" from an estate - the original owner had died and the estate agent thought the bike had never been ridden. It looked brand new to me - BUT the stem/handlebar arrangement was non-standard. There was a riser that I removed. The stem is one of the 'adjustable' Specialized stems that you can shim and turn over to get a variety of angles and heights.
My headset says FSA so I assume it is the stock headset - it does look like the headset shown in the Roubaix Installation Guide.
