Thanks guys ! Rel. new ceramic bearings, Hed Ardennes clincher wheel, Spinstix skewer, brand new Michelin Pro 4 Service course tire, ~ 100 psi, wheel is ~ 4-5 yrs. old but I will retire it hopefully next week when my Enve comes in. I BTW became an enthusiastic fan of Enve carbon tubulars. Just finished a ride in the N. Ga mountains ("gaps" as peaople know it around here), flew through a pothole, Enve couldn't have cared less, no damage, solid as a rock.Later on, I ran through a rock and flatted my front wheel, fortunately the rear one was not affected (tubular). I will have my bike, fork and headset checked out on Thursday and go from there.Yes, there was some play in the front wheel but I am not convinced that that is the real problem since I rode this same front wheel on my previous bikes.
