what pinion is the best 4 the rb5 1 that will be good

all pinions should work fine on the rb5

what motor and spur will you be using?

A pinion is for life, not just an RB5 :thumbsup:

We'll need to know what motor type and wind and track type to help.

As a guide, I use 20/78 on an LRP 6.5 brushless most places and 23/78 on a speed passion 9.5 indoors on tight slippery tracks.

its a novak 6.5 is 21 pinion good 2 use or not

depends on your track. what surface and how big/small, twisty/flowing is it?

It it's big and flowing then a 21 should be just ok. If it's a small twisty indoor track then probably drop to a 19.

what size spur as well
