I was shocked to discover a crack in my seat post clamp today. I thought Thomson products were more or less indestructible. Or at least of some of the highest quality parts available. But I guess everything can fail. Strangely, too, it doesn’t seem like a part that would have much stress put upon it through normal riding conditions. I rode home hoping that the seat clamp would hold until I got there (it did). I removed it. It didn’t seem to be overtightened. It seems to be the right size. So strange. Thomson offers a three year warranty on seat post clamps. I don’t remember exactly when I got it but I think it was a little longer than that. So I’m back to the original quick release clamp on Mindful Mule. I got the Thomson clamp after my seat and seat post were stolen a few years ago while using the quick release clamp. I generally don’t park my bike in compromised settings anymore so maybe I’ll just stick with the old clamp. Too bad—I thought the Thomson looked sharp.
