What would be the point of multiple gears if you don't use them when encountering hilly terrain to reduce fatigue? Isn't that what they were made for? I was just stating my opinion that knowing I have additional gears will make me more willing to gear down to reduce fatigue.

I encountered fixed gear after returning to the US and before that all i did was downhill mountain biking and long tours and went fixed because i like the extra challenge and feeling of accomplishment on longer rides and big hills. and plus its tons more fun than riding geared bikes and its easier to get into it and riding even when not going on longer rides. and now i wanna do fixed downhill mountain biking with a 29er.
