Finally riding a big boys bike
I ordered inner tubes from Amazon for Raleigh Record and Schwinn World Sport. Both had flat front tires. More on that later. What they delivered was https://www.amazon.com/dp/B000AAYBI2?psc=1&ref=ppx_yo2ov_dt_b_product_details. I immediately noticed the tubes had an ID much larger than the 27" wheel. WTF? I used them anyway and they seem to work out OK. Earlier I had replaced the rear inner tube on the world sport which I bought in town. It's i.d. was about the same as the rims o.d. so I was confused by how much larger the i.d. of the new tubes were than the rims o.d. The printing on the tubes did say for 27 X 1-1/8, 1-1/4. I looked on the box and that's when I saw 'also for 700c.
About the flats. I had just aired up our cars tires to spec and continued to the bikes. Both had only 25psi in the front tires so I aired them up in stages to 90 psi. I heard a pop on the Records front tire and I thought that was from the tire. It seemed to hold air and I rode it a few hundred feet. I returned to ride it 15 minutes later it and that tire was dead flat. I removed the tube to repair it, but it was too far gone. it had come apart along the mold lines and was oozing with green slime (it was an old bike I bought recently} Does Slime deteriorate innertube rubber?
