DID is an OEM of many Japanese and European brands.

Leading racing teams in the Road and off-road sports rely on the technology of DID.

The new 520DZ2 has been specially developed for use in trail and motocross applications.

Their low weight ensures a reduction of the moving masses while maintaining a high tensile strength.

In addition, rivets produced by a special process (SDH), which have a high surface hardness, speak for the 520DZ.
