well i just went for a 30 mile ride today, lucky i got that far.
i stopped at a coffee shop in the city and had some tea, after about an hour i realized my rear was flat.
so, at exactly 316.1 miles on conti ultrasports, i have had 4 flats....

NICE! i cant even trust them for short rides. luckly i had a spare tube so i just biked to my friends house and was brought home.
dont think i trust my bike enough to ride it until i get new tires, i think its time to officially retire the ultrasports.

the rear tire tread felt about as thin as the tube itself, i cant believe i had a slow leak and not a blowout, talk about lucky
