Guys,
Thanks so much for all your input.
The final answer for me is: I'll buy the bike.
Yes I totally agree that the main intention for me to buy the bike is to have fun riding it...and while I can appreciate that everyone has different opinions, for me to personally spend $5K for a bike and only riding it on the weekend sounds ridiculous.
So yes by knowing the fact now that carbon + alloy combination wheels are pretty strong I'll decide to buy it.
Cheers and thanks so much for all of your inputs,
Steve
