OK... I have been meaning to BUMP this thread for a while now...

Just before the Road Cycling Nationals last year (October 2007) my son (competing in U17 time trial and road race) asked me to cut his hair. I think this decision was based on aerodynamics rather than weight.

I really didn't want too, he looked great with long hair... It was down between his shoulders... measuring from the base of his hairline on his neck it was just on 10cm long.

So I gave him a number 4... arrrgh... it was hard...

But we gathered it all up and weighed it. Dry it was 250grams.
Unfortunately, it was thrown out before I could weigh it wet

So there you go... 1/2pound or 250grams if your hair is below your shoulders (and dry)...
