Subject: got burned being the nice guy last night my girlfriend and i were on our way home on the lakefront trail here in chicago and about 5 miles from home a guy with a brand new shiny road bike was walking and had a flat, so i stopped and asked if he needed help. He just bought the bike last week and had no tube or no pump and had never changed a flat before. I use my spare tube and changed his tire for him and he rides off into the sunset (literally, it was about 8pm ). so my girlfriend and I continue riding toward home and within 2 miles it was so dark i did not see a huge pot hole and pow, get a flat. we stop and i change that really quick and use the last CO2 cartridge doing it, which barely put 75 lbs in the tire.. I get on my bike and very quickly realize my front was flat too and had no more tubes. We enjoyed a nice walk home for the next couple of miles. Just though i would the story and realized i have to start patching these tubes instead of buying new ones. Do patches hold 120psi in? If so, are some patches better than others? |
