I have a 09 specialized sequia with a 9 speed cassette. Does anybody know if I can upgrade this bike to a 10 speed.
You can do it since a 10-speed Shimano or SRAM will fit your current rear hub. However, (and it's an expensive however) you will need to replace your brifters and chain too. The brifters will be the expensive part.
Sure, most anything's possible. I don't think it makes a whole lot of sense for those extra 2 or 3 gears, though.
Why do you think you need so many gears? Are you a racer? The average rider doesn't need any more than about 12-18 speeds. Leave your 9-speed be, you would just be wasting money for this "upgrade"
Without being snarky, the answer is "yes". You will need, at minimum, the following:
10-speed right side shifter. Here's one from Ebay: http://cgi.ebay.com/Shimano-105-5600...3A1%7C294%3A50
Truthfully, your money would be better spent upgrading your wheels- for about $200 you can get some Ultegra/OpenPro wheels that will be noticeably better than the original Alex wheels the Sequoia comes with.

Thanks for the info. I really dislike the sora shifters that came with this bike. I found a complete 105 set up that was a new take-off of a friends bike. It is however a ten speed. thanks again for all the help
