How much does your bike weigh?

I would suggest a 120kg should be looking at their own weight before worrying about the bike :-)

I am a bit of a weight weenie and this year decided to see if I could get my weight down. I managed to lose 7kg and get down to 70kg which for me is fairly lean at 178cm.
The point of the story is that it hasn't really made any noticeable difference when riding (possibly slightly faster uphill but that just because I am fitter than in the winter) yet 7kg is the weight of a whole bike.
But for some reason I am still obsessing a bit over a few hundred grams on wheels, forks etc,. so it is clearly a mental issue!

Ah, but rotational weight is worth more than any other sort, so (ignoring any fitness implications) you're better off saving 300g on your wheels than on your body.
