I'm looking for the smallest toothcount size available for 130mm spacing. I currently have a 39 tooth cog and I'm looking to go smaller. can any tell me if there is a smaller size than 38T and who would supply a smaller size. It does not have to be ramped, it will be used for SS.
Excel has a 38DougSloan

I've wanted to try a 38T, but Shimano recommends no more than a 14T difference in the chainrings (i.e. 39/53 is the biggest spread you should try).

Will one tooth make me a better climber or a mechanical disaster?

And the Salsa rings aren't ramped (I don't think). How big of a difference will that make?

I have successfully used a 53-38 combo with a Dura-Ace front derailleur (8spd 7400 series) and 9spd chain.

It will only make you a better climber if you gear out and have to mash up hills now, but even then only a small amount.

They don't put ramps on the inside ring, only the big ring of a double. You are talking about double chainrings, right?
