having recently made the switch from 7005 aluminum to a mix of sl and sp columbus these are my impressions
steel.
haha jk.
both bikes had carbon Handlebars and full carbon forks.
The aluminum was lighter but the ride quality was very "buzzy" if you get my drift and I had to wear gloves or my elbows would be toast, I live in New Orleans, some of the worst roads you will encounter.
Honestly and it may be in my head I think steel is more responsive in my case and the vibrations are less pronounced, I went from 14. 5 pounds with my old aluminum to almost 16 and barely notice the difference when putting it on the wall rack.
Also as far as personal preference I like the look of lugged steel to the oversized welded aluminum tunes.
and steel.
