I have a cannondale mountain bike. I want to change my conventional handle bars to time trial bars. The problem im facing is keeping my old shifters and brake levers.

Are you talking about road time trial bars? If you are, you shouldn't have too much trouble changing over to indexing bar end shifters. You won't be able to keep your grip shift or rapid fire shifters, they just won't be very efficient and would just look stupid. You may be able to just switch the whole thing over to a road setup with the road brake levers and bar end shifters. I helped a friend switch his mountain bars over to standard drop road bars and the only problem we had was the diameter of the bar at the stem was differant and took some coersion to get it done, but it worked like a charm. The other option may be add-on down tube shifters and road brake levers on the drop portion of the time trial bars. Good luck. Sorry, I didn't really answer yur question the way you asked it. It's 6 am and i've been up all night. I really don't think there would be an effective way to keep your OLD equipment. Consider switching over to all road stuff. they do work well and in the TT position they're right where you need them. You're right a-tool is a dumbass.

You are indeed a crazy Mexican! Time trial bars don't belong on MTB's; but...
Shimano shifting systems use a 2:1 actuation ratio, and some SRAM components use a 1:1 ratio. Therefore, you will be able to use road bike [racer] shifters as these will be positioned correctly [ergonomically] for TT bars and will work with your MTB derailleur (campagnolo, sr suntor also use 1:1 I believe).
Racer bike levers will not work with V-brakes though, as the mechanical advantage of the levers is different. You will either have to reach back to the normal bars to brake or change to cantilever/horseshoe brakes and use TT bar levers. Horse-shoe brakes will not work with fat tyres though so cantilevers may be your only option, they will work fine as long as you don't need to brake in an emergency ever!

You will also find out that the stem uses different sizing for mountain bars vs road bars (unless you have an OS mountain bike stem).
I also don't know if you can use road triggers on mountain deraileurs, I think they use different pull rations (not necesary cog teeths, which are completely different in a road bike).
Good luck!
