One of the nice things about the Alfine is it takes any 3 lug gear hub sprocket from Sturmey, Shimano or Sachs/Sram and others, I am currently running the offset 24 tooth Sachs 3/32" wide sprocket that gives a nice 42mm chainline. I believe Sturmey made a 26 tooth that takes 1/8" chain so the gearing choices really very wide.
I have not seen an SA sprocket bigger than 24T but do have a Sram the same fitting that is 25T
I am surprised no one asked what inspired this build, the answer is the 1948 R.R.A.
Like my Alfine hubbed Raleigh Royal.
