8.5T blinky, what pinion on TM2
 

Sorry if im lazy and im not that brilliant at math.

but 24t pinion, is that ok to use on TM2 v2 stock spurgear.

Something like 24t - 25t should be fine as a starting point

I run a 26 with a 7.5 at stotfold
I'd start with 26 no boost/turbo then add turbo if it's slow

I ran around a 26 with a boosted Orion 8.5 in my TM2V2
