I'm a newbie here, but when I lived in Colorado for about 10yrs, I was a serious rider. Couple of century rides, trips into the mountains, that sort of thing. Pretty much, I did my own servicing. Now, I'm old and fat for lack of activity, and my bike is just old, so I donated it to Goodwill. Yeah, it kinda hurt.
My wife and I decided to be less fat, though not less old, by getting a couple of bikes again. We went to a big box store (yes, I know, but it's all we could do) a couple of months back and got what to me looked like the best option for us.
So, here's the issue. I have a feeling I know what's going on, but feedback is always nice. We've been able to get out several times for rides. My wife likes short slow rides, when I'm alone, I can't stop myself from riding like I used to, so mine has more miles on it. As soon as we got the bikes I noticed that the tire would only hold an acceptable pressure in the tires for a couple of weeks. I did the usual: test the stems, inflate and check for bubbles, run the liners, run the insides of the tires. Nada. All 4 tubes are CST, which, from all the 'five star' opinions, seems to have a good rep for their tires, but when I went to search for the tubes, I couldn't find any info. I suspect that CST tubes blow, or leak, as is the case here -- particularly I suspect this because of where we got the bikes. I'm thinking there's a quality problem with these tubes, and I need to get all new tubes. Can any one give me feedback on CST tubes? Am I on the right track?
I'd be grateful for any direction. I don't mine reinflating the tires each time we use the bikes, but I sure don't enjoy it!
