The XSC1.0 is machined from 7075 alloy which removes about as much material as possible to still allow it to do its job. What's left weighs just 8g.
It comes in the two most common seat tube diameters of 31.8mm and 34.9mm. Providing you haven't got too thick a paintjob it'll slip on snugly, stopping as the internal lip rests on top of the tube.
Plenty of material has been left around the bolt area to resist cracking from loosening and tightening though you don't have to apply too much torque as the clamp provides plenty of pressure for the seatpost and frame interaction.
It's priced at £15.99 which can be considered expensive when you can get cheap cast clamps for a few quid but up against other super light machined clamps it's about on the money.
Overall the Aerozine XSC1.0 is a neat finishing product for customising your frame. It looks good and fits well and on the whole is priced well too. The option of eight various colours means one should match your bike too.

i have the 'superlight' Token clamp, 13.5g, I've not found any issues as yet after a year, I weigh 100kg and ride with gusto shall we say. Wanting to use something like this with bugger all meat is silly IMO.
I agree with some of the others, those weight weenie clamps are pure crap, they're too fragile to actually be serious about clamping. I bought one of those against my better judgement and it broke too, much better off getting a heavier stainless steel, or an AL collar with a stainless insert and bolt instead and deal with the extra 20 or so grams.
I have one of these, hope im not going to have a similar problem to lisa76uk.
Have a red one which looks killer on my black & red bike, been on for 20 months so feel ive had my £16 worth.
Their ceramic bottom bracket is fantastic value at £45 as well, also popped that on my steed in glorious red.
Ha! yeah, I know, it did look good while it lasted though
Your main mistake there was in thinking you were supposed to actually ride around on this, rather than only putting it on for the picture of your bike hanging from a scale.
Weird. I fitted one of these in March last year. My seatpost starting slipping recently, not by much, but enough to be annoying. I had a look yesterday and found it had cracked (see attachment). It had always been torqued to 6Nm which is within tolerance of the clamp and my carbon seatpost.

I wonder how much a normal £3 clamp weighs? 25/30g?
Probably ok if your seatpost is a perfect snug fit in your frame. If the frame is reamed slightly too big, or seatpost slightly undersized, this clamp doesn't look beefy enough to secure it.
I just went through the same problem on a Tripster ATR, only thing that sorted it was a Salsa Lip-Lock
