A very wise man once asked me if I knew the most important part on a road bike. I paused and thought and then responded the cranks? He said wrong. I then said the wheels and he quickly said wrong. When I was out of guesses he said "By far the most important part of any bike is the engine!!" And at that moment the light bulb went off for me. I own some great carbon fiber bikes with high end compnents and an SRM power meter on every one. None of them make me go faster than good bikes that cost a lot less. What I will tell you about bikes is that fit is really important. I no longer choose bikes by what I have read about the brand. I buy them solely base upon fit and after many years I know the exact specs that work for my body.
Having said all this there appears to be a direct correlation between new bikes and the amount that people ride. And since this is the case for most, it's a really good thing!!
Now somewhere in here is a lesson for us skiers. My skiing got to a level last year where I could ski the most difficult terrain at my home mountain in all conditions and on a variety of different skis. What I noticed was that technique had a lot more to do with how I skied it than what ski I was on.
Of cousre this forum was founded as an equipment forum. No one is more guilty that I am for buying new skis that I don't need. So who ami I to tell anyone they shouldn't be buying new skis or that new skis might not help in certain conditions. To some degree they will but never as much as improved technique!!
