The tongue port bar has an especially flattened shape to the port. This gives the tongue optimum room. Many horses respond to this with improved suppleness and increased chewing. This bit is also very well suited to horses that play with their tongues, trying to get their tongue over the bit, as the port effectively prevents this. With a height of 30mm, the port is fully permissible under German equestrian sport regulations. This mouthpiece is thus eminently suited to horses that do not tolerate traditionally shaped bits due to the pressure on the tongue and react by head-shaking or similar. The Tandem US is almost identical to the regular Tandem. With its elegant, black nose band it is favoured for use at sales and demonstration events.
