Over the past 3 years since buying my bike I have spent about $3000 on the bike, parts, and servicing. I've done in excess of 10,000km (I'm a rec rider, not training for races etc).
So per km my bike has cost me 30c/km. I go out for a 100km bike ride and effectively that costs me $30.
(yes I understand the longer I keep my bike the cheaper it gets, but I'm about to have to service the BB and right brifter soon).
I think $30 is a lot for an enjoyable 3-4 hour bit of exercise. When I was single and renting is was loose change to buy the bike. Now I have a mortage buying a new bike of the same standard is a huge hurdle .
In many motor sport grades they have looked at ways to make things cheaper so more people could afford to particapate, but I can't see this working in cycling. You can buy a bike and put 10,000km on it for less than I paid. OK the bike isn't as nice but it will still do the job.
Cycling has a huge snob factor to it. The better you get the bigger the snobs you tend to end up riding with. We are also greedy and want those lovely expensive bikes (human nature).
The fact is the bikes we on this website (all bike snobs to some degree) consider junk are better bikes than won the TdF back in the 80s.
Will a 105/veloce equiped bike, with Al frame and carbon fork do 10,000km (with servicing)? YES! Will it be more cost effective than a bike 3 times its price? YES! Will it be 3 times slower or 3 times less reliable? NO!
The fact is to get a certian level of "performance" you have to pay a certian price. But the bikes performa at a much higher standard these days as well.
If you have the money and want to spend it, go for it...........if you don't then learn to live with what you can afford, stop complaining, and ride the wheels off it and enjoy passing middle aged men on thier over priced bikes!
BTW maybe bikes are costing so much more in the states because the bottom has fallen out of the USD
