wobble

[admin]

I just changed my front tire[same size ect.] just a new tire. I had my local dealer balance it.Now my bike wobbles baddly from the moment I start rolling.The wheel is true within .015"horizontally and vertically. The tire itself is within .050"horizotally and .015" vertically. What could have changed?

I guess the tire is seated on the rim properly, judging by the runout numbers. You didn't put a radial on the front, with a bias ply on the back, by any chance, did you? That will cause havoc!

I've never run a radial much less mixed em,, effexer could be right on, check that...
Otherwise, the the first thing I'd look at is to make ABSOLUTLY sure that the bead IS properly seated...
Did the dealer re-install the wheel/tire back on the sickle.? I've run them backwards by mistake(my mistake) by re-installing in the wrong direction, but I didn't even know it till I checked something else hundreds of miles later, in-other-words, no change in the ride, however, it could make a diff on yours though, so check that... I bet you've looked over the unit well, no loose nuts, spacers in their correct location, etc... Did the mech do anything else, re-adjust neck bearings, etc. anything...???

Mag or spoke wheel? Reason I ask is at one point I had a tube installed in a tubeless mag. I got a flat afterwards and when I brought wheel in for a repair they installed a new tube WITHOUT REMOVING THE OLD ONE! Hows that for stupid? Apparently the old tube some how bunched up and they never saw it in there. They just slapped a new tube in. I mounted the wheel and made it a half a block and the front was jumpin up and down like a pogo stick. Imagine how pissed I was to have to remove the wheel again and bring it back. Needless to say the guy who did it made the wall "Jackass of the month" nice pic too for everyone to see. You cant make this stuff up.
