understanding 3 speed gearbox conversions

[Mike Costigan]

I'm with you on this one, Bob. My RM with standard 3-speed and 4.9 diff matches a 4-speed RP under most circumstances - better in some places, not so good in others, but it evens out over a run. I certainly wouldn't want a higher bottom gear in Derbyshire, on some of our local runs it can be touch-and-go whether I can make some inclines!
