Dynamic RS Single Joint Eggbutt




4040878 - Sprenger Dynamic RS Eggbutt, Single Jointed, Sensogan






  • Adapted to the anatomy of the horse’s mouth.
  • No pressure put on the palate.
  • Clear instructions given as the tongue’s sense of touch is utilised.
  • Made from SENSOGAN the approved metal for horses 

The eggbutt version of this bit encourages acceptance of the bit and
rider’s contact in addition to the advantages mentioned above. The
mouthpiece remains in a central position to direct gentle pressure
perfectly on the tongue.



 About the Dynamic RS Mouthpiece

Stimulates the horse to accept the bit more easily

The ergonomically formed mouthpiece lies perfectly in the horses mouth
resulting in soft and even pressure on the entire tongue area,
encouraging the horse to chew. In addition this bit supports the contact
to the corners of the mouth in a very effective way keeping the horse
on the bit.

The gentle joint in the middle which is angled forward – the
characteristic feature of the KK ULTRA and fine eggbutt design makes it
a very friendly bit. The mouthpiece is made of SENSOGAN, the material
that activates the chewing activity of the horse.

The new DYNAMIC RS bit gives soft but very effective instructions for a better contact between the horse and rider.



SENSOGAN® is a new bit
material developed by SPRENGER and is the result of two years of research and
development aiming to improve on the AURIGAN material which has made SPRENGER
bits so popular with so many professional and amateur riders.


improved properties but also a new appearance. The white-gold colour gives the
bit a discreet and elegant look and due to the improved material mix, SENSOGAN®
does not tarnish easily as the chewing activity of the horse is optimally
supported. The bit will stay true to its white gold colour for much longer and
can also be polished to a high shine at any point in its lifetime. The new
SENSOGAN® range is identified by its unique stamped black ring on the cheeks of
the mouthpieces.



The special
challenge in developing SENSOGAN® was to maintain the positive features of
Aurigan yet to intensify them, giving an even more delicate and sophisticated
connection to the horse. In the twenty or so years that Aurigan has been
available, many companies have copied its colour but never its properties.
Sprenger knew the time was right to launch their new optimal bitting collection
with an unmatched look anywhere else in the market.



It is the
distinctive composition of Copper, Manganese and Zinc that makes SENSOGAN® so
special. The reduced copper content combined with the manganese results in a
more regulated process of oxidation. Tests with the veterinary college of
Hannover and the German Riding School in Warendorf  showed without doubt this
combination of metals has a positive influence on the horses satisfaction,
motivation and willingness to perform.



Manganese is known
to assist with building up connective tissue as well as for muscle and energy
metabolism, it is also known to reduce histamine and can help prevent skin
reactions. The feed industry has recently recognised manganese as an important
feed additive for competition horses.



Available in a wide
range of the popular bit styles and sizes from Sprenger including the KK Ultra,
Dynamic RS, WH Ultra and Turnado ranges, plus many other individual weymouths,
bradoons and jumping and training bits. Different bit rings can also be ordered
to match stainless steel or bronze coloured bridle work.






Important Information


Make sure the bit is fitted correctly in the mouth. The arrow must always be on the left hand side pointing forwards.
