Inno Sense Full Cheek Mullen
The Full Cheek has two vertical rods on a fixed ring. These straight bars(toggles) provide more side pressure (against the cheek), making steering easier. The ring of the Full Cheek is smaller than that of the D-shaped bit with less leverage effect as a result. The upper toggles of the TRUST Full Cheek are slightly curved outwards so that they do not get stuck under the noseband.
The Inno Sense Mullen is a straight bar that slightly bends forward. This mouthpiece is
fabricated of synthetic material. The bit has a rigid core that makes the mullen bar not flexible but the material around it still gives the bit a soft touch.
