Re: pic: Four Speed Three CIM Gearbox

To me, the big "why" is why have four speeds over about a total 3:1 high-to-low ratio? If you're going to bother with four speeds, spread them out a bit wider!

At a minimum, I would put the shifts a factor of 2:1 apart, resulting in an 8:1 overall ratio from high to low. At a "standard" 2.56:1 ratio between shifts, the total range would be 16.77:1. At 3:1 per shift, it would be a massive 27:1, which could be a real game changer in some highly defensive games or games with steep ramps. Especially if you want to reserve some CIMs for manipulators!
