“3 out of the 4 tubes failed at the valve... really poor quality product. Not sure if i received a bad batch or they were old stock?”
“What can I say? It's an inner tube with a long stem.
But from 99 Bikes it was very cheap and easy to order and pick up.”
“So far so good. 5 long days riding on gravel and no issues.”
“Strong tubes. Do their job.”
