That's very cool Ash. As long as the lockring is tight and pressure applied
to squeeze it all together , there's not anymore to it. I found this

Replies #6 and #7. This one from Crankypants : " *I know a 12t lockring
will work on a non-serrated 2nd position cog as I've been using just that
on a bike for over 12k miles with a 13t cog. I would think the 11t lockring
would also work but possibly the smaller diameter may be an issue but I
doubt it. Just make sure you tighten the lockring properly and then check
it after the first couple of rides to make sure it stays tight and if no
problems you should be good to go."*
I too like riding in larger chainrings. say 44t and above. There is a
definite unique feel to big rings and large-r cogs compared to the same
gear-inch with a small ring and small-er cogs. My thinking about gearing
with the advent of up to 50t cassette cogs has sorta been turned upside
down. I could see riding just a say 34/46 double with a wide range
cassette, a 40, 42, 46 or even 50 cog. You can get very low gear without a
24/26t granny ring, which frankly I've never liked riding in, it's always
felt odd. Riding up steep hills in say a 36t ring/32t cog gear always feels
better than the equivalent granny gear.
