I recently popped the tube in my front tire and need help replacing it. I don't really know very much about bikes or the assortment of numbers on tubes, tires, and wheels. Here is what I do know:
The tire that popped has 700x35/43C on it.
The spare that I got when I bought the bike has A2 25/32 x 622/635 on it.
I was told that the spare is not the right size for my bike. I inflated it just a bit to see what it looked like in my tire and it does seem a bit small as it looks like it has a bit of room. .
I just got a spare tube that has a schrader valve and learned that those cannot fit through the hole in my wheel. I'm not sure but I think this is the type of tube I need to get http://www.amazon.com/Avenir-Bicycle-Presta-25-35c-27-Inch/dp/B002K2DQ4S/ref=sr_1_10?s=cycling&ie=UTF8&qid=1337452869&sr=1-10 700 x 35-45c or 700 x 25-35c as I was told I need 35 to be in the range of the second set of numbers. Is this correct? Can I get these with a presta valve in a store (like Target, Walmart, etc local large merchant) or should I just order and wait?
For additional info: My actual wheel says it is 622x17 6061H-T6. On the inside of the wheel groove it looks like it is stamped 900x16. It looks like the tire name and brand is Alexrims G6000. It is a hybrid bike.
