Asking if anyone is against steel on a fixie/ss board is like asking if anyone dislikes carbon on the roadie board.

Part of the ethos of riding fixed or singlespeed is basic, fundamnetal, retrospective etc. That usually means steel as it's the oldest and most refined building material, and fits the ideaology. Titanium is tollerated because, well, it just rocks and kind of looks like steel that someone forgot to paint, but Aluminium frankly reminds us of the slab of beer we drank last night.

Initially satisfying, but eventually crumpled up in our recycling bin and us feeling like sh1t.
