SB Sport Gearing
 

Could anyone tell me what spur and pinion to go for running a Checkpoint 10x2 in the SB Sport please.
Cheers for any help, Dave

I would go 24/70.

indoors i ran 17 on kit spur, but you will need to file the motor mount to get the mesh

outdoors i ran 19 on a reedy stle motor so id say no more than 22 on the checkpoint

I ran 22 before and it was undergeared, 23 then, might be slightly different with the new cells we run.

Thanks for the help guys.

With a little modification you can use associated spur gears and slipper pads. If you want pics let me know, it's not hard.
