Hello my name is Heidi. I started road biking on 16 Sept 2006...the day I bought my Trek...so I am still new. I have a lot of trouble with my tires...the innertubes...currently I am using Truegoo self sealing innertubes. I put a new innertube in my front tire today and twenty miles into my ride I have a flat in the front again. No thorns or goatheads etc... I am closing the valve stem back up when I put air in the tire.
I have two innertubes that don't hold air but I can't find a hole in either one. I won the lottery for Ride the Rockies and I need to educate myself on tires and innertubes...any suggestions?
Thank you
Heidi
