to be honest i cant find any 1/8" chainrings in anything smaller than 144mm, and thus any smaller than 42T.
I dont care its a "Track" component but i figured single speed people liked 1/8" for some reason so i was looking for that
i have heard 1/8" would pop off less.

Yeah 21T is the largest i can get, this is going on my Sturmey 3sp and thats as big as they come without hacking stuff together.
As for the gearing I was hoping for 38/21 in the winter then I would switch to an 16T or 18T once winter is over. 38 isnt an absolute number its just my ideal.

I might just end up buying this becuase it is the lowest sized front i can find, but its looks cheesy, its only 44T.
