|Shrader (Car tire valve)|
After I got the tube in, I tightened that screw on the Presta valve right tight to the frame of the rim. And off I went.. for a few days. Then the tire started to get low. So I pumped it up. 2 days later, the tire is flat again. So I pumped it up. 1 day later, the tire is flat. So I pumped it up.. but this was starting to get annoying. So I went back to the bike shop where I got the tube installed and inquired if the new "presta" valve were a little leaker then the older style.. The employee looked at me like I had two heads.. but then answered the question. (which was no..)
So after buying a longer steam for the handle bars, I left the store and would you believe it.. My tire was FLAT.. and well, on the ground.
I waltz back into the store and asked if they had time to look at the bike, as the for mentioned tire issue just appeared again. The clerk looked at the clock and said he didn't have any time.. then I convinced him to at least pump up the tire with his compressor, which should get me home at least.. Still had another 30km to go. Going to the store was really out of my way.
So the clerk tried to put air in my tire and he discovered that my valve had ripped right off from the tube. I mean, right off! So no matter how much air.. it's going to go flat, fast. The clerk took pitty on me and decided to work on the bike after all. Which I was VERY thankful for. (Plug Tall Tree Cycles is an amazing store with very helpful people)
And off I went, this time I left the nut loose so it could go up and down a bit, when I hit a pot hole.. I'm still filling up the new tube every two/three days but I think the presta valve on the replacement, replacement, tube is warped. I bought another tube from ebay (again Surley) and I'm hoping to have some time to get them to put that one in... Each time, costing me about $40.
- Always have a spare tube.
- Always check the pressure of the tire before riding.
- Don't tighten the nut on the Presta valve, give it some slack.
- The motor should have a quick release connector from the bike, other wise it's a major pain to do your own tube replacements. With no quick disconnect, the job is a two person job.. one to hold the tire in place and the other to do the actual tire replacement.
