Well titanium screws and a carbon bottle cage won't make a difference. But if you do 100 little things it adds up to a BIG thing. If you aren't seriously racing it's stupid to spend money on something that will not benifit you. When training, it would be better to ride a heavier bike like said above in that it will make you stronger. Then you could have a light racing bike on the side. Then again, if your filthy stinkin rich go and buy what you want-you poser!
