I dont believe they have a special name as such, very much depends where you buy them usually- I know Mikes pinions are super smooth with both metal and plastic spurs. Another thing worth noting is that unless the pinions are hardened steel, they will wear down very rapidly against the hardend steel spurs that are standard on most nitros.
The difference between the 2 pinions shown is the pressure angle I think, BrianG?
