Re: Re:

OK Ian, thanks hopefully.

Sorry, all my 20t rings have the same hole pattern as the 22s so it doesn't look hopeful I'm afraid.

Re:

I've sourced a NOS Boone Titanium 22t with "slotted" holes, just don't ask the price :facepalm: but need another!

Never had wear problems myself with the proper SunTour plated steel inner rings, similar to Sakae Ninja. I would imagine alloy wouldn't last long...

Yes It was the Alloy outer and inners that wore fast, compared to the 48/38 rings that were the "mainstream" rings of choice.

Re:

For those interested, managed to scour the Worlds' bike shops and found this Boone Titanium one, cost as much as a set of half decent cranks, but couldn't complete my NOS RS-1 cranks without it and it is lighter than ally and tougher.

Note the slotted chain ring bolt holes!

STILL NEED ANOTHER ANYONE???
