Mavic Ksyrium Elite S wheels with Mavic Griplink and Powerlink tires (previous units were Shimano RS10's and dirt cheap Forte 28c tires), Ultegra 11 speed upgrade.....which included an 11-32 cassette, a new rear derailleur, a new right side brifter, and new Ultegra chain (previous drivetrain was 10speed Ultegra 6700). All of that lead me to a new left side brifter, as the older Ultegra didn't match the new brifter, and a pro bike fit.
I think I'm done for awhile.
