Thomson seatposts are notorious for slipping if you have a google.
Interesting that your Thomson clamp resolved it though.
I won't buy another Thomson seatpost.
Oh, i always thought it was a clamp issue and not a seatpost one. Maybe it was my post all along.
I know the Hope clamps have weak bolts. Never tried the Salsa bolt clamp, but I know many swear by them
Who knows! Could be either I guess. I just had that issue with mine and have since read about other people having the same issue and it's always seems to be a thomson post.
