Guys,

I have a late '60's Peugeot U08 with the beautifully swept chrome front fork tubes. Others on this forum have spoken as to the nice handling of these vintage bikes. I love my U08, but would disagree regarding the handling. I consider the handling to be extremely quick and a little "darty." Tracking perfectly strainght in a draft line requires concentration.

This bike came originally with something like a 27" x 1 -3/8" wheel and tire. Over the years I have changed the wheels and now have a nice semi-aero 700 x 23 laced to 105 Shimano hubs front and rear.

My question is this: How much has handling been affected by the change in wheel/tires? Is it due to a change in geometry or merely the change in the amount of tire "contact patch?"

Hope this post is clear. I am a frequent "lurker" and have learned an amazing amount from others on this forum.

Thanks,

Tyson
