yes both work

also getting a racing variator for a TGB will give you some more speed/top end & more
aggressive take off depending on the ramps.

So 17x13mm fit in a tgb variator?
I'm just confirming.
Thanks

And i keep hearing mixed things about sizes.
That they are 17x12.3, but 17x12 work fine
And then even 13mm fit  too? Any light you could shed would be very appreciated

just look online

also try using sliders instead of rollers.
