Ok I have a BIG question here. What is the story about todays inner tubes?? yesterday had other flat on my one varsity that was just sitting
On that bike have brand NEW kenda road tires. MY LBS sells Serfs tubes and keeps giving my 700X28-133 Keeps telling me that 27x1-1/4 are obsolete. Any way this is the 3rd flat on this bike in a month and its been sitting There is NOTHING in the tire. THE leaks are coming from the tube seams. Tried Kenda 700x28/32c and had the same thing after a few weeks goes flat were the seems are. Also I have FOUR original schwinn tubes form the 70s sitting here and you can see that they are much more thicker AND NOT AS skinny as the 700x28-133. Right now on my 73 varsity I have the Schwalbe HA 159 tires and a set of sunlite tubes size 27x1-1/4 that the LBS shop had a few of them They so far are holding up. As of yesterday I have 675 miles on my Schwalbe tires since aug 2. I think the 27 inch size is the main thing. BUT I remember as a kid living in Southern California back in the 60s I had a 10 speed varsity and i rode that thing all over and NEVER had a flat. Today I think the thicker tubes were why. So now that I have the bullet proof schwalbe tires I am now looking to find thicker and better 27x1-1/4 tubes. Also if this size is obsolete then I going to be buying two more sets of the schwalbe this week then next month buy more and do the same with the tubes when I find what I am looking for why are todays tubes so thin like paper and why are they pushing out the 27 inch size???
