I presume you have an issue with the new #5 Tri-dex?
I recently had a problem with the Tri-dex that came with my SST 5 LX shoes, but all I had to do was make sure the red portion was below the middle white segment.
I bought a pair of SST6 LX over three years ago and the original #5 didn't go more than 7-8 months before it started grabbing too much. The first Tri-dex I bought was just like the original #5 was from the start.
It still works like I expect it to, it's just a lot wider than what I need on the SST 5. I might cut it down for a later date.
