Just got an email from Dressage Canada, the verbindend is not legal this year. They will accept it if it is on the FEI list . It is not yet.
I competed in it last year and it is sold in some Canadian tack shops as dressage legal, which is quite misleading! Guess I now have to invest in a new snaffle
It is ALWAYS up to the competitor to ensure with their Federation that equipment is legal.
I would never ever count on what a tack store says. I would not count on what anyone in this forum says. Go straight to the Federation.
Bumping this thread back up, because I just saw this blurb about Neue Schule bits on Dressage Daily. Bear in mind, articles like this are paid advertising, but it may provide some useful info for those of you wondering about the bits.
