OK, so I bought them and I thought I'd tell the rest of the forum to give these a miss. I have managed to attach them to my daily ride and they work OK I suppose, but there is no way you can get 26 mm tyres with them. The blades are wide enough, but there are some really clumsy large plastic contraptions between the blades and the pins. They will scrape against a 25mm tyre.
I've fortunately got 23mm tyres anyway so I can use them, but on the whole it's a silly silly product.
