Claim:
Toothed chain with alternating inner and outer chain links, the inner chain links comprising at least one inner plate and at least two joint bushes running perpendicularly through the same, the outer chain links comprising at least two outer plates and at least two joint pins running perpendicularly through the same, the alternating inner and outer chain links being joined by a chain joint defined by one of the at least two joint pins of the outer chain link extending through a corresponding one of the at least two joint bushes of the inner chain link, wherein at least one inner plate of the inner chain link and/or at least one outer plate of the outer chain link is embodied as a toothed plate with each two teeth defined by an outer flank, and wherein an external flank angle given for two external flanks of the toothed plate, is α≧65° and ≦75°, and a ratio V Ba between a pitch p of the toothed chain and an outer diameter d Ba of the joint pins is ≦2.65 and ≧2.15.
