I just grinded mine. There was no easy way of getting no-chamfer one, unless you were ready to wait for weeks for shop to order them (and pay A LOT). Doesn't look that nice as yours, but still works fine
One of reason why I hate Sram with passion is lack of their (on-line) service manuals. For my bike it's no big deal as I have Shimano, but my wife's bike has Sram and I would need to fix few things, but no idea where to even start
So if you don't mind, is there chance to send me link where they do have real service manuals (Shimano has web with all, service, user and dealer manuals freely available). I, and especially my wife, would be eternally grateful if I could get rid of weird noise in her BB
