Somehow this old thread was recycled. I still have the same knock on Menards tubular that I had a few years ago. The metal is too thin and does not make good contact with the pins. I've tested different batches in the stores each season and they don't seem to be able to get a handle on this issue with their supplier. Some batches are good but most of the tracks I test in the store have loose track pins that cannot be tightened even if you squeeze them tight with a track pliers.
