The stock base bar on my new TT bike (P2) is pretty crappy and uncomfortable, so I'm looking at changing it.

I'm a big believer in the 'buy quality or buy it twice', so looking to upgrade to a decent front end, extensions and all.

I'm tossing up between carbon and aluminium.

I don't care about bling (although a neat and tidy setup would be nice), and a few grams here or there isn't going to make a huge difference to me.

I would have thought that a carbon cockpit would absorb road buzz better than aluminium, which I see as the main advantage. You really feel every bump when in the aerobar position.

However, the thought of catastrophic carbon failure (which has happened to a guy I know on a roadbike and has put me off carbon road handlebars forever) is a pretty scary one.

So the main questions are:
1. Do carbon TT bar setups absorb vibration significantly better than aluminium?
2. Do carbon TT bars fail more, or less than carbon road handlebars?

Have done a quick search, but not found anything on the forums to date.
