Can I use this bit in dressage?

[Pidge]

Ok so think I have finally solved the brakes issue with Pidge as bought this bit yesterday http://www.derbyhouse.co.uk/prodshow.asp?id=1922&cat=2&scats=50
and took him XC schooling today and actually had brakes and could get him to do some nice canter work in control

However I don't know if you can use it in dressage comps? It would only be local unaffiliated ones. Please help?

Unfortunately no, a copper roller is not dressage legal.

didn't think it would be, thanks for confirming it
