AJ R is correct. we took extra sprockets of the same pitch and cut out most of the material for weight. they are pushed into the chain and adjusted by pushing them closer to the drive or driven sprockets.
we have had on a few occasions that the impact forces through the drive train have shattered one of the more aggressively lightened sprockets.
