As already said on this thread, top-end is top-end and it costs.
I've notced a couple of things in cycle prices over the past 20 years or so...
1. People who are 'new' to the pursuit and may only be involved for a few years go straight for high-end stuff in a way I don't recall that sort doing 20 years ago. I don't know why this is.
2. I suspect that in real terms prices are higher. In the early 80s a friend had a bespoke, high-end bike put together at
Condor for about £350. At the time that was an absurd amount of money, but the bike was quite delicious. Most of us rode, but we all had standard Dawes, Raleigh or similar 5-speed or 10-speed stuff. At that time a school-leaver was earning maybe £70/80 per week. So... a posh Condor for 5 weeks' money for a school-leaver.
What would that machine cost now (updated to current spec). A condor ground-up bike can cost easily £4500-£5000, but I don't imagine many school-leavers are pulling in a grand a week.
3. Volumes for high-end stuff are greater now; Campagnolo transmissions were a rarity outside the full-on cycling community 20 or 30 years ago... now you see scores of them at every station car park. this should bring prices down, but it hasn't.
Cycling is 'sexy' in a way it really wasn't 30 years ago (apart from among a few die-hards). The market will charge what the market can bear. We are all willing to pay these barmy prices and as long as we are prices will continue as they are.
I don't like spending money and I save it where I can, but I do love to ride the smooth, swish, light bicycle that money buys me.
I'd like to resent it, but somehow I can't.
