upgrade on drivetrain ?yammi

i own a lemond alpe'duez with a shimano 105 groupset,triple
chainring.i have a number of ?.i'm a mountainbiker ,buying the lemond 6 months ago purely for training purposes.but now,i'm considering doing some road races next year,including training rides with local clubs to "learn the
ropes".would it be any advantage to switch over to a doudle chainring from a triple considreing a no longer use the smallest ring.would i have better shifting efficiency?if i do it i was only going to replace the drivetrain,not the shifters or brakes.for $300 i can upgrade to a dura ace.would this be worth the investment or a complete waste of time and money?should i just run the 105's until their shot? if i upgrade it will not be until early spring, but i thought i'd throw the ? out here now. i have no delusions about how upgrading will make me faster, only solid training will allow that to happen.

Nothing wrong with 105. Run them till they're shot then get D/A if you can afford it.

I would upgrade if you can afford it.. Your 105 shifters will probably run and run !
Save the 105 shifters and start trying to put together a second training/winter/indoor-trainer bike.
105 makes good replacement parts for when you wreck!Canidraftyou

Keep the 105 for spare parts, dont sell them so that the cost of up grading is less of a blow. Im talking more on the shifters, for they are the first to go in most cases.

Its only my opinion. The most important upgrade is finding the correct Cassette to run. To many people use what everyone else is running. Dont listen to those that say you need this combo or that combo. YOU NEED TO RUN WHAT YOUR ABLE TO RUN!!! This is how alot of people get beat on the sprint or blow knees. They have too much gear or not enough. Find a selection of cogs for climbing and find a set for the flats. I have four sets of cassettes. I use the 11-23 DA. It works for me. May not be the cassette for you. In time, you'll find a cassette that works nice for both mountain and flats.

If money is not an issue, then Dura Ace all the way.
