I like my Aluminum pedals. But I do have to say that the brake pedal is slippery. Especially when wet, but also when dry. I guess that I typically keep my foot just on the right edge of the pedal when at a stop. But when I do that, my foots slides off all the time. So I now need to move to press more on the center of the pedal. It's actually little uncomfortable for me. Nitpicking, I know. I have been trying to think of what I could do to make it less slippery. Maybe roughing up the edge or finding a rubber applique I could put on that area. I think if they had rubber on the edge, as opposed to aluminum, it would be fine.
But I like the look a lot. I'd like an aluminum dead pedal. But they are outrageously prices, from what I have found.
