How many teeth do they have?

I have a number of different color coded gears. Which do you guys run with what spur for high speed track or low speed ones etc.

ok these are the combos that work together

20/24 with 52/48
21/25 with 52/48
22/26 with 52/48
23/27 with 52/48

20/26 with 54/48
21/27 with 54/48

20/24 with 54/50
21/25 with 54/50
22/26 with 54/50
23/27 with 54/50

if you dont use these combos then you will most likely strip a spur gear because the gear mesh will be incorrect

you can either run a 4 gear split or a 6 gear split. I usually run a 6 20/26 pinion grey/black and a 48/54 spur. depending on the track and tire size.The spur gears are stamped with the size. Hope this helps...

RRacer: can you elaborate on what you said more? im pretty new to this. whats a 4 and 6 gear split.

The pionion gears vs. the spur gears..

20/26 - 54/48

6 - 6

I believe the 6 tooth split is good for big tracks that are prepped and
true permanent road courses, for smaller courses like the electics run,
the 4 tooth split seems better as the car doesn't jump and twitch with the shift points.

So I believe the size of the track is also a consideration

what combo do you guys run in a big high speed track and a small tight track?

For a wide open track, I use 21-27 and 54-48
If you are on a small track, you can actually use a 2 count or a 4 count split.
That will keep you in you power band a little better.
