The Trust Inno Sense Ported Cartwheel Bit combines a synthetic ported mouthpiece with cartwheel sides.
The mouthpiece attaches to a post running vertically through the centre of the bit rings (hence the 'Cartwheel'), giving a slight tilting action. Cartwheels can often be suitable for horses that are difficult to turn, because the rings enhance steering aids by placing pressure on the horse's face. It also creates more positive poll pressure then a plain beval bit, as the mouthpiece runs on a straight bar rather than on bit rings.
The synthetic ported mouthpiece is ergonomically shaped to allow space for the horse's tongue, and is available in Medium or Hard densities.
Available in 12.5cm (just under 5in), 13.5cm (5 1/4in) or 14.5cm (5 3/4in).
