This was pointed out in a thread on the Clyde forum, and I had the same question as you...here's the answer:
From the Specialized Bikes Owner's Manual, page 35:
"All adult adult Specialized Bicycles are designed and tested for a maximum combined rider /cargo /bike weight of 100Kg.
Please visit the OWNER’s manual section of our website (
www.specialized.com/tech) for Intended Use Categories and model-specific maximum weights . In some cases weight limits are higher than 100Kg."
Specialized 2009 Owners Manual
If you go the website for further info, you can get model-specific weight limits here:

This quote may be more interesting:
"Road and mountain bikes with carbon frames have a STRUCTURAL weight limit of 275lb / 125kg. If carbon components (e.g. handlebars,
seat posts, stems, etc) are present, then the weight limit is 240lb / 109kg. IMPORTANT: Road bike braking limits do not change
regardless of carbon or alloy components."
