In my case, the upgrade placebo wasn't tires, it is a new mountainbike handlebar for my old Schwinn LeTour. I just now finished the job of replacing the old dropbars with the new mtb handlebars and new cane creek crosstop brake levers. My Schinn has a big smile on her face. I'll take pictures tomorrow when it's daylight...after my 21 mile commute.
