All sprockets for off-road use are built in 16CrNi4 and where possible lightened.

The particular steel used guarantees an excellent durability of the pinion and the entire transmission.

The products with the word 'unloaded' indicate an additional machining of the pinion tooth to facilitate the discharge of the sludge under heavy use conditions, thus increasing the duration of the transmission.

The high quality of the materials used, of the production technology and of the strict quality controls that each individual product undergoes have made the CHT material a quality reference in the sector over the years.
