Just ask Becky how much difference the switch from the Bridgestones to the Avon Venoms made with her riding. To me she looked like she gained 10 years of riding experience when I was behind her through the curves up Mingus Mountain. If you want long life out of your tires, get the Metzler 880s. Not as sticky as the Venoms, but still a big improvement over the Bridgestones from the reports in here. I run the 880s front and back and I like them. Good enough for me and the way I ride(7/10).
