Okay here is a stupid yet genunine question. My last bike which I rode 20 years ago only had 3 gears if I remember rightly and I never used them. When I started on my new bike about 3 weeks ago I went every where in number 2 as I found the others too hard. As I am getting a bit fitter I am moving up into 3 and now mostly 4. So my question is this. Is it better to pedal slower in a higher gear ie 4 or 5 or faster in a lower gear ie 2 or 3?
