DID is the OEM for many Japanese and European brands. Direct race road and off-road sport teams rely on technology DID.
DID ZVM - X: as the successor to the proven high-performance chain ZVM2 was in the development of. attention ZVM - X on the various constraints that occur in life daily tensile strength is in this case only the calculated static laboratory the breaking load on a string, but not resistance to the forces that occur in practice.
so mainly the force was placed at the centre in use at the ZVM - X. , increased resistance to traction and, weighing less than ZVM2 to
very high wear resistance and a setting to 50% reduction of friction losses due to the patented X-ring plates outside money, silver Interior plates (S & S = Silver and silver)
