KCNC constructs their KCNC S10 Quick Release Seat Collar with a bushing-less spherical cam. Using this system, the KCNC SC10 seat collar has a consistently smooth, durable and powerful closure. KCNC manufacturers the SC10 from 7075 aluminum with a titanium shaft for a combination of strength and light weight. To make things even lighter, KCNC machined all unnecessary material without sacrificing strength. The finish is anodized with laser cut logos.
This is a very well-made piece. The lever action is very smooth. And is a great solution if your ride style requires your seat adjusted up and down (like switching from trail riding to jumps) and you don't mind stopping for a second to make that adjustment. It's much quicker than digging for your Allen wrench:)
PROS: Durable, Attractive Design, Lightweight, Easy To Install
CONS: On The High-end Of The Price Range
BEST USES: Racing, Mountain Biking, Casual Riding, BMX, Upgrade
This thing is worlds lighter than any other QR I've owned. It closes smoothly, and clamps well. The blue is a shade lighter than most blue anodized parts, but it still looks great. Held up well so far.
I ordered this KCNC Ti seatpost clamp along with the KCNC Ti skewers. Just like the skewers, the seatpost clamp weighed in less than advertised - 23g advertised vs. 19g actual. You have to tighten the clamp nut down pretty good to get enough clamping force to hold the post firm but it does it's job with absolute minimal weight. It's also an incredibly nicely machined piece.
What to say, its lighter than most of whats out there, and I prefer the smaller handle too. Theres no rubber bearing so the fit is firm. I did notice I need to tighten it a bit more than my old one, but I also did upgrade seat post that has horizontal milling, so I'm guessing its just that. Has not caused a problem, and its more on theme with the rest of my bike now. (also recently ordered KCNC Ti Skewers. Great products)

This thing is simple, and strong. Has great holding power. The lever takes a bit getting used to. However, it works great. Ti bolt, a huge brass shim, and hi grade aluminum make this a perfect replacement for those that dont have the a dropper post.
My Azonic clamp was worthless, and this replaced it. WAY better.
If your looking for a long lasting clamp, this is it.
