A special steel was used for the production of sprockets, which is then precisely heat-treated under strict control to values, thanks to which a great combination of strength and hardness is achieved.
Modern production technology allows to achieve high dimensional accuracy for easy and fast assembly.
The sprockets are supplied perforated or solid, but their quality and functionality remain the same.
