My Bianchi came with an aluminum 6-notch lockring, which I promptly damaged with my single-prong Sugino tool, which is a close relative of the Hozan shown above. Fortunately, my LBS had a 6-prong puller, so we removed the damaged ring with that. Also fortunately, I had saved the steel 3-prong lockring from my first Bianchi, which is what I now use. Big lesson: when you scrap any bicycle or major component, save the small bits and fittings, because you never know when they will come in handy in the future. I saved an Agrati pedal dustcap from my first Capo after the frame finally broke, only to find that my third Capo was missing one.
