Robinson Racing "Six Pack" 48P Odd Pinion Pack (15,17,19,21,23,25T)
Don't last very long. Only good to work out what teeth count works best for you so you can buy a better quality pinion in that size.
Teeth aren't stamped/engraved on but it is only a 6 pack. Put them together and work out which one is bigger or smaller.)
