Alright here is the deal. I am at a stoplight, I take off. There is a "Crest" in the intersection--hopefully you know what I am talking about. I take off anyway, and I get this wobble in the front tire. Felt like the bike's front tire was hoping from one side to the other. I had a good tight grip on the bars so nothing bad happened, but freaked me out a little bit. I added a couple psi in both tires that was all I had changed recently. I think up to 36psi. All I can come up with is that the front tire got light as I crested the "hill" in the intersection, but I was below 8grand on the tach--so I wasn't really making all that much power.
