I managed to puncture a Foss tube last night on the San Francisco Randonneurs Russian River 300k brevet. I've ridden about 700 miles on the Hilsen since putting medium 650b Foss tubes with Hetres. It was a big thorn that got me. It's hard to say exactly how long it took to lose enough air to catch my attention, but it sure seemed from the time I found it to be excessively squishy to the time I found it essentially unrideable was only a few minutes. It was after dark at about mile 165, so I was trying to limp into Fairfax so I could have light and a cup of coffee while I fixed it. I tried pumping it up, but it was leaking too fast. I had the Fossy sticker patches, so the fix was quick. The thorn was still in the tire, but I didn't get a great look at it in the dark. I just picked it out and it landed on the ground. I had been running 40psi in front, and 45 in back.
I'm not reaching any conclusions based on this one flat. It's just one flat. But I know some of you want reports of this type. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
