Robinson Racing "Aluminum Pro" 64P Pinion Gear (60T)
Received the item and the pinion gear itself doesnt have the screw threads for the grub screw, although the hole is there. Contacted RR and they were not apologetic about it. Not happy with them.

Robinson Racing "Aluminum Pro" 64P Pinion Gear (46T)
I have a few different brands of a pinions and Robinson is my favorite.
The robinson pinions unlike most have straight cut teeth all the way across with no chamfered edge (like a spur gear), so the entire tooth length engages with the entire width of the spur teeth. This also makes the Robinson gear width thinner than most, giving you the most clearance.
The one "con" is the set screw is 1/16th and not 1.5mm - you will strip it out quickly using a 1.5mm hex...
