They are similar to TD pro race 1.2 but cheaper...

I have them on my Haynes Roadster. I never had any problem with them. They look good (I think), and seem light too.
I'm happy with them so far, and I can recommend them.
I'm using my Roadster on road only though, no race or track day.
Hope the will help
