So, neither of these two are remotely mostly original. Not that it matters after 40 years, but wow. Another "this'll do.." parts swap affair. Naturally, with this being a 715 also (of 1982 flavor), a comparison must be done.
But first, when in doubt about fixing a delaminating tire,

Extra places for extra security and strength. And yes, I did test ride it like this! 45 PSI again (lol). Brakes worked great!
Can't get enough of that glue job, but look, a slick SR Aero X crankset!
