I have never been asked about my weight, but I figure they size me up when they look at me. How do you find out what the weight limit is for the various parts of your bike? I don't recall seeing anything in any specs- do you dig deep into that big bag of techy documents that come with a new bike? I admit to being nervous that I am on the heavier side for my snazzy carbon bike- the carbon seatpost makes me especially nervous. I am about 20 lbs overweight, but am still a smaller person- but I do worry my bike is rated for someone who is 110 lbs or something! I wouldn't have even thought to worry about aluminum or steel.

And yes, things do get personal! I am still trying to figure how to explain to my (very cute) LBS guy that the seat on my new bike is causing some major discomfort- no, not in the butt...more "to the front" from there!
