At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
Carrying on the anodised colour coding of their other components this XSC1.0 seatclamp from Aerozine is about as minimal as you get. One for the weight weenies.
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.
Weight-weenie seatclamp available in loads of colours and two sizes

As part of the Tech Hub here at F-At Digital, our senior product reviewer Stu uses the knowledge gained from putting well over a 1,000 products through their paces (including hundreds of bikes) to write in-depth reviews of a huge range of kit. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 160,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him he still likes to smash the pedals rather than take things easy. Although, as he spends a fair bit of his time reviewing ebikes these days he's becoming an expert in letting the motor take the strain. He's also waiting for 23mm race tyres to make a comeback!
