Hello All, Last summer was my son's first season. We ran a sealed clone/fixed sprocket size class at our local track. Switching to 206 for the coming season and planning on doing ckna schedule in addition to local races. Looking to sort what drivers/sprockets I should have on hand. What gear ratio range will we need to be able to cover? What's the typical step size made between ratios. Still newbies and not looking to get a truck load of gears but want to be able to get in the ballpark. thanks!
