well...i found a site about bike equipment called weight weenies...and i was perusing the sight, figure out where i can cut weight and how much weight i can cut on either my road or tri bike. but is it worth it? if i went ALL OUT and dropped thousands and thousands of dollars...i can cut MAYBE 5 lbs from my bike. but i mean...it's 5-6 freaking pounds! will that really make an appreciable difference? honestly? i mean shoot...my weight fluctuates 10 lbs from month to month...sometimes i can lose or gain 10 lbs in a week!
now...i do remember from physics class that rotational mass matters more. if i spent a ridiculous amount of money...rims, tires, spokes, etc...i can cut maybe 2 lbs of rotational mass. can you feel that? will that significantly improve my splits?
