Winderen, the company behind the Gel Bits System, is based in Zamość, Poland. Its mouthpieces are a synthetic gel over a core, which Winderen says horses accept readily and which stands up well to chewing. The gel carries FDA certification.
What sets Winderen apart is that mouthpieces and cheekpieces are interchangeable. You can buy a complete bit, or buy a mouthpiece and the cheeks separately and swap them in a few moments. If your horse is happy in one mouthpiece, you can change the cheek without taking away what it has already accepted.
Start with the mouthpiece thickness. Winderen makes two:
Then the mouthpiece shape. We stock the flexi mullen, the double broken mullen (a hybrid of a double jointed and a mullen mouthpiece) and stainless steel single and double jointed mouthpieces.
Cheeks include eggbutt, D-ring, baucher and full cheek snaffles, 2.5 ring, American, eggbutt and full cheek gags, baby Pelham, baby Swales and baby curb cheeks, full size curbs and a Kimblewick. You will find complete Winderen bits and mouthpieces and cheekpieces sold separately on their own pages. Winderen says the system was designed to meet FEI rules, though it is always worth checking with your own federation.
Our bit fitting checklist will help you size a Winderen mouthpiece. Winderen bits are sold outright and are not part of the Bit Bank trial.
