word is that many track coaches say not to apply any back pressure at all. ever.

i guess that makes sense, people push much bigger gears on the track.

edit: yup, try both kinds of lockring. the thread pitch is the same for italian and iso/english, it's the diameter that's different. if the english doesn't fit at all, then it's italian. if they both fit, but the english feels more snug it's english.
