Heard a guy at the co-op say disc rotors are 'consumables now'...
Was at a bike co-op in Seattle last weekend and overheard this older mechanic telling a new guy that rotors should be treated like brake pads. Just throw them away when they get thin or warped. I always figured you could at least true a rotor a few times before replacing it. He said with how cheap Tektro and Shimano rotors are now, it's not worth the time to straighten them. But I've got a set of old 203mm Hope rotors that have lasted me 4 years across two bikes... what do you guys think, are we really past the point of truing rotors?

Oh please, it's not that serious. I've been truing rotors with an adjustable wrench for years and they work fine, just gotta have a light touch.

Trued a set of old 180mm Avid rotors last month with a crescent wrench, worked fine. They had a little wobble after a hard ride and I just bent them back slow and careful, took maybe five minutes. Then again, those were nicer rotors to begin with, not the cheap stamped ones you see now. I think it depends on what you're starting with, some of the budget stuff really is junk from the jump.
