I’m trying to get my new to me HED 3 wheels ready for my first ever time trial. I glued up the Conti Sprinter tires and pulled the valve core to add some Orange Seal. When I pulled the core, the small O ring on the inside got caught up and tore. I ditched it and used plumbers tape on the threads. They held air fine for a few days.
I went to top them up this weekend and after 20 min it went flat. My question is what should I do to fix it? Pull the core and re tape? I only used one wrap so maybe two would be better? Buy a conti tube, pull the core and use that as a replacement? I assume it would fit with no issues. The TT is on Wednesday afternoon so I have bit of time to get it fixed.
