I have read through the thread and did not read anything about this question I have. My Mercier Nano is on its way from bikesdirect. I definitely want to upgrade the handlebars to some short and shallow compact bars. My question is since the effective TT is 3.5cm shorter than my cyclocross bike should I use handlebars that are wider to accommodate the handlebars being closer to me?
I posed this question in the fitting forum in much more detail and got no response.

...Thought I might have better luck here.
