I tightened the clamp to 3nm on both bolts and have ridden 290 miles since without any slippage. That post is locked in. Be sure to clean up your seat post and apply carbon paste)lube (the gritty stuff) before clamping. Very happy with this purchase.
This double-bolt seat clamp solved a problem both my wife and I were having on our bikes. Tightened to the full 6 Nm the single-bolt seat clamps that came with our bikes wasn't enough to keep our seat posts from slipping down. These double-bolt seat clamps, each bolt tightened to 3 Nm, has fixed the problem! Using these you do want to tighten each bolt a little bit at a time until they are both equally and fully tight. In the picture below, the tape on the seat post hasn't budged after hundreds of bumpy miles, which is, sadly, more than I can say for the single-bolt Wolf Tooth seat post clamp that came with the bike.
Both bolts snapped at 6Nm- so I changed them out with stronger steel bolts
Got 34.9mm seat post, worked well, but 36.9mm Death Grip seat post clamp did not fit over the seat frame Need a slightly larger diameter to work
I ordered a seat post , 34.9 mm. It fits great. But you do Not offer seat post clamp that would be slightly larger, to work on my Specialized Levo SL Carbon.
Please consider making seat post clamps that would work with your very nice seat posts
