Most of my riding is off road so this isnt an issue - when I am on the open road I have to be sitting on about 117km/h to be doing 100km/h. Result is that I am aware that I am running that much higher in revs. As far as 1st and 2nd gear is concerned I find that the gearing suits me fine in the hills that I ride in. Yes - they will be shorter - I think 2nd now is probably closer to first with standard gearing just based on feel.

Since I am only planning on going up to a 46t, do you think that my 2nd gear will be as low as yours? Thanks.
