Review: Works for tall rails - Fits tall rails. Unfortunately the bolt sometimes doesn’t hold if you are on the nose of the saddle and hit a big bump. I’m only 130 lbs. be nice if the bolt was titanium as it’s pretty heavy
Review: Does the job perfectly - Have a scott gravel 10 that I wanted to upgrade to a lighter carbon fizik argo 00 adaptive saddle with 7/9 rails. Bought this little clamp and it was super easy top swap in.

## Questions & Answers

**Q: Is the inner channel (with rubber thing) required when installing this with 7x9.6 Fizik oval carbon rails?**
A: Yes. You need the inner rubber piece.

**Q: Totally new to this so don't laugh if it's a dumb question. But do you need a post that will accommodate a 1 bolt clamp or is that irrelevant?**
A: You will need a one bolt seat post.

**Q: What torque should be used for carbon rails...the clamp saids 12nm...wouldnt 12nm crack the rails?  Thanks!**
A: My answer will definitely be different than the others. At 12nM, the carbon rails of my saddle get a little warped and skews a little to the left, and I've more than a few bolts going to 12nM. I weight 240, and 10nM has been plenty to keep the saddle in place, and help protect my saddle rails a little more

**Q: hi, i jave a selle italian seat with a 7x9 carbokeramic rails, is this clamp compatible with the carbon rails 7x9 ?**
A: No, this is the one for 7mm dia. alloy rails, not the tall, rectangular carbon ones like you have.  Definitely don't use this one as it can damage the carbon rails.
