I concur, mine make my bike feel more fun to ride and it is 1/2 pound lighter. More fun means I ride more and enjoy riding more.
Yep; at the end of the day this about fun for all but a very few who are riding professionally. There have been mornings when having a new whatever on my bike caused me to get out of bed instead of hitting the snooze button. Maybe I'm lame that way but it matters to me and I spend my money where I get value as defined by me.
A point about wheelset prices; 2500 bucks isn't the price point for carbon wheelsets anymore, there are plenty of choice for 1000 bucks US that are well manufactured and safe. My Aeolus Pro 3V ended up being about 1500 Canadian with discs, cassette and taxes.
True, but this does not mean that a $1250 set of carbon wheels are the same as a $2500 set. I have Aeolus XXX 2's which are really close in weight to G23's and for me were a lot cheaper due to an industry connection.
My other passion is cars; I find it interesting that the choice arguments online are very similar. Yes, a Mustang GT is very fast, certainly fast enough but folks will spend 5X that on a Ferrari (or whatever) that is only marginally faster. In the end, buy what you like, where the value lies for you. What gets old are the implications that those who buy the more expensive option are uninformed/stupid/wasting their money; that is simply not the case, they just see a different value proposition. I see folks spend lots of money on things that I just don't understand at all like pickups that never haul anything or go off pavement..At least cycling gear contributes to being healthy!
