I got 16, 17 and 18t. Currently running 46/17 on the left side of the bike with 145mm cranks.

I think the splines are the same as Shimano Cassette cogs.
The new S3x uses a 9 spline pattern (like Shimano cassettes) but have been told it is not compatible with Shimano cassette cogs... thinking that it might use 9 identical splines like the old Uniglide.

I will have to look up those cog specs although one would not want to run a ramped cog with shorter teeth on a fixed drive anyways.
