Hello all,

Figured this is a good place to ask. I have this bike:



It currently has a full 7-speed Shimano 105 groupset which works just fine, yet I am still considering upgrading it. First I thought of getting a modern drivetrain with 'brifters,' but now I've decided that I want to keep the downtube shifters, because I like the look and they are fun to operate. Now I am thinking to upgrade to full Dura Ace, just because. This is what I am thinking of currently:

- 7900 downtube shifters. I like the idea of having ten speeds so that I can use modern wheels.
- 7800 RD. Works with the downtube shifters (right?) and is silver. Also, it can be had for cheap.
- 7410 FD. Seems to be the only one I can easily find with a 28.6mm clamp.

For the rest, I would like some DA brake calipers and DA aero brake levers. Am I right to think that the 7402 levers are what I am looking for? Or is there anything more recent? Would any calipers work with 7400 levers? Would 7700 calipers work? I like the looks of those.

Is there any part of my plan that won't work? Any parts that you would recommend instead of those I have mentioned? Thanks for the help.
