I am new member here and sad to read some thoughts about disappointment. I register current trend in decrease of posts, discussions and members on boards elsewhere too. And that trend came with increase of popularity of social networks. But anyway, you still have new or old members returning who might not discuss in the same passion than before, but search and read what was written and open new topics as well (even though with lower frequency).
I am planning to totally rebuild my CAAD10, but when I look at it from the higher perspective, it won't be too much innovative. It's just about searching for parts available in the market which will match very nicely together. But at the same time I will try to be different a little bit to other CAADs. I hope everything will go fine and I will expand collection of CAADs here with another nice piece.
When tuning my bike I have to consider durability of components, apart from their weight. Our roads (in my country) are not nice, with many potholes. Because of that, in my opinion, training on some LW wheels or other nice, but fragile, ones won't be good idea. Same applies to frame, drivetrain, etc.
Yes, light parts may be durable, when you do your research, experiment... that's where all the knowledge which have been gathered here comes in hand. That's why I am here and like to study what was covered here
For instance, I currently think about sanding FSA cranks to get rid of the decals I don't like, in order to make the look of my CAAD cleaner. Or, if I didn't want it do myself, I may look for someone's help and buy already sanded cranks and have no worries (if there were any for sale).
