Finally got around to fitting the Leyo paddles and been driving with them for about a week now.
They appear to be top quality and fitting took 5 minutes, the only thing I did was Loctite the two screws - not sure you really need too but I felt happier doing it. They fit perfectly.
In all the pictures I've seen the two screws are at the top whereas the pair that arrived have them at the bottom which means they can't been seen in normal use. I did notice the box said "Gen2" so I guess there has been a slight redesign.
On the road they are great to use and I've found myself manually changing gear far more often because you are not restricted to 9-3 like the originals. I did notice that the bottom half inch is redundant due to the angle with the pivot which means you cant physically operate the paddle but I've read that about all paddles so it's not unique to Leyo.
