Casseroll can accommodate a triple crankset...

I'm not sure if the Double Cross is going to like a triple...

however...
the DC can take MTB wheels... (think 29er)
and with all the new SRAM MTB groupos being offered up at 2x10...

on that note:
I'd pick the Double Cross, use a set of MAVIC SpeedCitys, and SRAM Apex groupo with Avid disc brakes (road caliper), matched up to a gear combo of 50/34 x 32/11t

as to handlebars... I'd think about a set of titec J-bars...

as to bags.... I'd think about frame bags, in the BikePacking technique
