The new Scott's QR stock Seat clamp weighs a Ton! 41gr, to be specie.

I don't trust the carbon solution for seat clamp! I'm looking for 10gr (+/-) 7075 Alu clamp with Ti Bolt.

That's what I have found:

Scott dealer does not have the bolt (old) version

Any other options ?

First of all you can really trust those carbon clamps! I use such clamps on all my bikes and never had any issues.

If you are looking for aluminium i think the lightest one would indeed be the Soul-Kozak but the standard clamp from the higher line Scotts weighs also just 14g

Then there is also this one:

supposedly 18g for the 38,0mm size.

Shown below::
Carbon clamp 38,0mm: 5,3g
Standard Scott clamp from Scale LTD / 10: 13,6g
Kohsis 38mm clamp

Still they look fragile to me… Will give it a thought.

As mentioned above already: durability is NOT an issue with any of these clamps. Price is as you pay a lot of money to save only a couple of grams.

Adi, just look what happened to mine seat clamp (has been used on my previouse Blur XC)

This clamp doesn't holds the seat post as good as aluminium one! Trust me! you don't want to stand up all the way back to home like i did, when overtight the clamp, becouse i don't keep a torque wrench in my camelbak.

Today i can use it as a key chain :madman:

Just use some carbon mounting paste at the seatpost.this redices the needed torque dramatically. You shouldn't need more than 3-5 N/m.
