Ah! just had some tinkering enter the equation that I DON'T like to do.

A rear wheel has a slow leak problem Originally flatted a few weeks ago while out riding. Replaced it on the road. After around five days of hanging on my wall I got it down to ride and the rear tire was squishy. Pumped it up and rode it to make sure there was a problem. A few days later, soft again. Damn.

Okay, took the tire totally off, checked for stuck debris and any big holes. None. Hole in the tube was so small I couldn't find it by sound or feel (going to have to put it in water, just haven't gotten to it). Put in a new tube, been riding for a week or two on it...just got it down to ride tomorrow...rear tire soft. AHHH! I also checked to make sure there aren't any spokes poking through.

So...now I'm punctured two brand new tubes, need to patch them, and I still have no idea what is digging into them. For me this tinkering is not relaxing - so many variables and every time I don't solve it that is another tube I need to patch or toss...

Oh well, life could be worse
