13T as 1st sprocket

[super slim]

Dear Wise Ladies, and Gentlemen, AND Jond,
I am wanting to replace my 11T sprocket with a 16T sprocket, to give me an extra gear between 20 and 30 kph!

I can't find a 13T Shimano 10 speed 1st position sprocket, or a Larger flanged Lock ring to suit the 13T knurled area of estimated 42 mm diameter.

I have found a 9 speed 13T 1st position sprocket.
Would this work if I file 0.5 mm off it width, to match the 10 speed spacing?!

Has anyone found a Shimano 13T lock ring?

Has anyone removed the 11T before?

13-29 10 speed. I think you can just use the 13 and whatever cog you need.
I have never tried it though. I think others have.

You might be able to use the AbsoluteBlack "13T Lockring".
From their website:
Compatibility: SLX * (CS-HG81-10 11-36), XT (CS-M771-10 11-36), XTR (CS-M980-10 11-36) 10 speed only.

look up Peter White Cycles under products, then drivetrain, then TA Podium Cassettes. Sells individual cogs & lockings. Should work well.

$30 to $100 AU PER item, irrespective of size or weight!!!!!!

Its a GREAT place to live, but expensive to fly parts to from USA!
Its Much cheaper getting parts from Great Britain, that's why we have SO many British Convicts here!!!!

They are a frame builder, so have a big range of individual cassette sprockets, and frame parts!
