I bought and used this product when I DISC the front brake of DAX.
Brake performance, etc., there was no problem, but the processing of Edge was lax.
I didn't think anything of it, but when I tried to wash it with my hand, it became a bloodbath.
So I took care of it by shaving the Rose and Edge with Diamond sandpaper.
They're reasonably priced, they look OEM-chic, and I was happy with them.
Edge finishes and such are sweet.
But that's what I would recommend if you know what you're doing from the get-go.
Looks like you access from European region.
Would you shop at webike.eu.com?
