I'm not looking for any more speed just lower revs when I travel long journeys.
Hope to hear your thoughts
With the gearing set up to give lower revs at speed I think you'd find there just isn't enough power. At the slightest incline you would be running in third gear much of the time. Forever dropping down a gear.
Remember you need power to maintain speed, and power is turning force multiplied by revs. You need revs to keep you going.
I find it easier to drive at 35, with resultant less revs, but think it would be better with a slightly lower gearing so changing into third less often.
jslater, do you live in a very flat area?
