With attention to detail and years of experience, Pessoa makes bits designed for the professional rider. Their Cherry Roller Copper Pelham is an excellent choice for very forward jumpers or horses that have more go than whoa.  With the swivel correction port, this bit offers quite a bit of stopping power, but also encourages relaxation with the smooth gliding copper rollers. Many horses find cherry rollers to be relaxing and the copper helps to improve mouth moisture as well.  Shorter Tom Thumb shanks minimize the leverage effect thereby creating a mild poll pressure and curb pressure.  Available in one size only 5.25″
