It just makes sense to me that if the rubber has to stretch too much it is under tension and it gets thinner so it's easier to puncture it. I have some 700x47's and tubes for 35mm tires that don't seem to hold air as long yet the same size tube using a 32mm tire seems to hold air much longer. I do

I have used 26x1.25-1.5 for Riv Nifty Swifty. It's a bit of stretch but no problem. I got those tubes from Universal Cyclery in Portland oregon. Franklyn On Feb 28, 1:48 pm, David Estes wrote: > On Sat, Feb 28, 2009 at 12:33 PM, Steve Palincsar wrote: > > > On Sat, 2009-02-28 at 11:53 -0800, L
