Jtek Seat Post Clamp with Screw Thread to stop slipping seat posts

[slowster]

I've just noticed this on SJS's ebay webshop. I think this is a new product, and it looks like it's another option for people with slipping seat posts. Although the product description refers to it being used with carbon seat posts, I presume that if it can be used safely with carbon then it is suitable for ordinary aluminium seat posts. Designed for 27.2mm seat posts and 31.8mm seat tubes. No reviews as yet on SJS's website.

The regular clamp secures the seatpost in the normal way but we all know that carbon seatposts have a tendency to slip down.
The screw threaded knurled top cap closes down on the post in the same way as a drill chuck holds a bit.

Clever.

It would be better if they just focussed on the sleeve part so that it could be used with conventional seatpost clamps, and of course, in other common sizes.
