The Universal cheek provides a number of rein options including the option of a curb strap. But whatever option you choose, the flattened underside of the FlexZ cannons with their anatomy-inspired recesses are held parallel to the tongue whatever riding activity you enjoy.
This innovation is brilliant for the over-active busy mouth that chomps and chews on the mouthpiece. Turtle TopTM with Flex keeps the mouthpiece centred and arched over the tongue at all times, safely helping to prevent sideways tongue evasions. This comfortable mouthpiece re-focuses the inattentive mouth back onto the rein aids in order to achieve a soft consistent contact.
