Got the pair of 700x23 GP4000 w/ Black Chili I ordered from PBK yesterday (ordered 3/30, received in MN on 4/6, not bad). Got them mounted this afternoon and went out for a 15 mile shorty just to try them out. I simply can't believe how much smoother and literally easier to pedal even my cheapa** Fuji Newest 4.0 is with these tires. I can't afford to upgrade this year but next year when I upgrade bikes you can bet your a** that these GP4000s will be the second thing (behind pedals) to get mounted. I was really looking to get a CAAD9 w/Ultegra...hopefully they'll still exist next year.

New tires...whodathunkit...amazing...
