I am looking to buy my first ever real (read: not from canadian tire) bicycle. I will be using it mostly for my 6km commute to work, but also for pleasure. Mostly roads, occasionally gravel. I am thinking of one of the following bikes... Opus urbano http://www.opusbike.com/site_route.php?lang=en or the Devinci st-tropez http://www.devinci.com/11048_an.html

I can't tell anything from looking at the specs or components, as I know nothing!
Which one is a better bike?

Cheers!
