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.

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'!).

The ergonomically formed mouthpiece lies perfectly in the horse's 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 the fine eggbutt design makes it a very friendly bit. The mouthpiece is made of AURIGAN, the material that activates the chewing activity of your horse. The new DYNAMIC RS bit gives soft but very effective instructions for a better contact between horse and rider. 

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.

The Herm Sprenger Dynamic RS Aurigan Eggbutt Style Bit is offered in mouth sizes 5", 5 1/4" or 5 3/4". 70mm flat stainless steel rings. 16mm thickness.

Rated 5 out of 5 by from PERFECT BIT Used this bit for several weeks on my TB mate and she responses wonderful to it.

Rated 4 out of 5 by from Great Bit! This is a lovely bit of great quality. I bought It for a mare who Is quite fussy in her mouth in other bits that I have tried. She absolutely loves this bit and responds well to It. My only complaints are that the eggbutt rings are more of a D-ring and I wish the bit was a bit lighter, but other than that the bit works great.

Rated 4 out of 5 by from It's ok This is very expensive, but my mare seems to like it just fine. It looks more like a D ring than an eggbutt though.

Rated 5 out of 5 by from Fabulous bit! I have a 21mm Sprenger loose ring snaffle that is about 30 years old and a wonderful bit. However, loose ring bits never seem to fit my mare well and will pinch. Have tried many widths and thickness but they just don't work for her. I purchased this bit as I know what excellent quality Herm Sprenger bits are having owned others. My horse tends to not chew much and will have a dry mouth but the Sprenger bits really encourage the production of saliva and chewing. This bit is a fabulous fit for my mare, she is soft and foamy. It is well worth the price and I know it will last a long time! My horse's comfort is what is most important to me so I don't mind the investment on a quality bit that will be used daily for many years to come.

Rated 5 out of 5 by from Beautiful bit, happy horse! I had been using Myler bits on my TB, which have worked great on my other horses- decided to spring for this beautiful bit-and this seems to be the right bit for him! Worth the money, if it's in your budget!
