I'm thinking of setting up some Campagnolo Ergo shifters on a bike and was wondering if I can run both the cables in the front of an ungrooved handlebar?
Will it be too bulky and uncomfortable? Should I track down some double grooved bars instead?
In general, do people route both cables in front or front and back?
To me it always seemed like it might be rough on the hands to have a cable running on the back of the bars.

Thoughts or suggestions anyone?
