We're bringing you this product at the lowest price allowed by the manufacturer so you won't find it cheaper anywhere else. This also means we can't apply any further discounts or promotions.
We're sorry, but certain colors/sizes are sold out and are no longer available.

As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

Why We Love This

The ergonomically formed mouthpiece allows a rapid and balanced effect on the tounge, 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 mouthpiece is made of AURIGAN, the material that activates the chewing activity of your horse. Dynamic RS bits encourage the horse to accept the bit more easily. In comparison to conventional single jointed bits Dynamic RS mouthpieces give even pressure on the entire tongue area. Dynamic RS bits represent  a better contact between the horse and ride. 

Favorite Features

  • Genuine patented Aurigan bits are manufactured only by Herm Sprenger
  • Aurigan is a perfect mixture of materials (85% copper, 4% silicon and 11% zinc)
  • Aurigan has high oxidation properties and provides a pleasant taste to encourage chewing activity and easy acceptance of the bit

Made in Germany

Herm Sprenger Dynamic RS Aurigan Loose Ring Single Jointed Bit is rated 4.8 out of 5 by 10.
Rated 5 out of 5 by from Fantastic bit!! I bought this bit for my 11 year old TB gelding, we'd been borrowing my trainer's older model Herm Sprenger and this model seemed to be the current version of what she had. This bit runs true to size, is a great medium weight, and the metal is amazing!! The older model I'd been borrowing for him was copper and he liked it, but he loves the Aurigan metal! He happily chews and salivates during our ride and actually reaches for it when I go to put it on! Overall definitely worth the price!

Rated 5 out of 5 by from Now, NOW, I have a happy mare. First of all, I should say, I'm on board with the whole aurigan thing. I've had two successive horses that have loved it. Also, my current mare moves beautifully in this bit and actually tries to hold onto it when I'm untacking. This has never happened to me before. The bit is a hit No doubt about it.

Rated 4 out of 5 by from Nice Quality Bit Nice quality bit, on the more expensive side but I was having trouble finding a plain loose ring snaffle. I think it runs a little bit small in comparison to the other loose rings I have but overall a nice quality piece to add to any bit collection. My horse went well in it too, I would just recommend ordering a size up

Rated 4 out of 5 by from great bit, if can spare the money The aurigan material definitely increased salivation in my horse, but I found that my horse goes just as well in her much less expensive copper mouth bit. I just didn't think it was worth all the extra money. Maybe I will purchases a used one someday.

Rated 5 out of 5 by from Nice bit I ordered several bits to try on the horse I am riding and this was his favorite. I was not inclined to try a single jointed bit, as I have always used bits with a bean or french link in the past, but I had a dressage judge recommend I try a single jointed bit so I did. My big guy likes this bit much better than all the other bits I tried. He foams and drools very nicely in this bit and has a relaxed jaw. Definately worth trying if you are not having any luck with the bean or french link bits.
