I was on my way home from a long trip and started to notice a wobble on my front end....I have about 8k miles on this tire and rim...i have a 21" DNA spoke rim with Vee Rubber tire... up to this point I have loved it....It is shaking just enough to cause some concern....it almost seems that something is off balance....any sugestions where to begin?

 

At what speed does it do it. Hands on the bars or off. Does it when speed decreasing? Heavy load up high and back?
Check your tire pressure, then check neck bearings, then check spokes.

 

If you have a spoke wheel on the rear check those. I had a bad wobble in the front of mine and it turned out to be the rear wheel.
