After searching for a while, my Google-Fu doesn't seem to be turning up the info that I've been looking for. I'm getting ready to build my first project bike and I'm deciding on a frame that I like. I am concerned about aesthetics, but not to the point of getting something that is impractical or ends up being a wall hanger. I really like the look of aluminum (ex: http://liverydesigngruppe.com/liveryblog/?cat=25 is the frame that I'm particularly interested in, local builder etc), but I haven't been able to find enough information on the pros and cons of riding aluminum vs steel. I've read a bunch of general assessments: Steel flexes and lasts longer, Aluminum is a stiffer ride but may have a short life due to metal fatigue, but I'm looking for a bit more hands on analysis.
Anyone have experience with this enough to be able to delineate the pros and cons of building up an Aluminum frame bike. I plan on using this bike to ride around town (attempting to only use my car to drive to and from work as I commute 60 miles a day to and from work), for errands and just for fun riding. One of my main concerns is that the streets in my city (Long Beach, CA) are not fantastic and running an aluminum frame/carbon fork combo seems risky if they really are as brittle and stiff as they seem to be.
I currently wrench on a Schwinn Le Tour III, which unfortunately is not worth converting as it spent a few years outside and it would need a complete overhaul. I've kept it in as good repair as I can, but it seems to be time for a new bike. So, any help would be appreciated. Thanks!
Oh, and inb4 "have you heard of the search button?" because it doesn't seem to work atm.
