Convert 9 speed to 10 speed
 

I have a 9 speed Shimano Deore LX hub and cassette. To change to 10 speed will I need:
New chain rings? Are 9 speed chain rings same as 10 speed?
New chain?
New hub or will the 10 sp cassette fit the present hub?
New Der?
New shifter? Yes
On present setup the biggest 9 sp cassette gear is 32 teeth . Looks like shimano 10 sp cassettes only go to 27. Can individual gears be fitted to these cassettes? I need the teeth.
Where does one buy the individual gears?
Thanks

You only need shifters,chain and cassette. There are no larger 10 speed cogs available. And, just what is the point to this??

Thank you for the info.

The Point of this?

I'm bored.
I like to spend money.
It seems I'm always a gear short or a gear long.
I like to keep pace with current technology as much as possible. It makes me feel good.
Like my computer, do I really need a 3 gig processor? Really I don't, but it feels good.

Consider an infaltable doll.Send me the money.

And, by the way, I would consider sending you money. What would you do for me? By the way, what is a INFALTABLE doll? Is that one with falts(faults)?
