It is here, the dressage legal version of the popular bit Alexander!

Tim is a sweet-tasting, double-jointed sweet iron Snaffle.

The joints are tilted 45 degrees and can be used in 2 ways:

With the horse logo on the right side running forward, the joints will follow the tongue to make the pressure in the tongue more gentle. This can be good for sensitive horses who need clear but gentle signals.

With the horse logo upside down on the left side running forward, the joints will give some more pressure on the tongue when you take the reins, but also more relief when you give the reins. This can be good for horses that are sensitive but where you want a quicker reaction.
The sweet iron material will still make your horse seek contact with the bit, while the joints will help you get clear signals.

Material
Sweet iron is a covering on top of a bit made of stainless steel. The purpose is to disguise the metal taste from stainless steel and create a pleasant, sweet taste, encouraging the horse to seek more contact and hold on to the bit. Following use, sweet iron will start to oxidize and turn brownish grey, this is to be expected.

Sweet iron is a good choice for horses who need to seek more contact with the bit.

Loose rings
Loose Rings are designed to move independently to the mouthpiece. This allows the horse more freedom to use his tongue, allowing them to place the pressure from the mouthpiece either higher or lower, whichever they prefer. Loose Rings are a good choice for a horse that can be slightly stiff or hard in the mouth.
