Got a Speed UNO recently and now want to mod it to have dual speed. What are your experiences, thoughts and suggestions with adding a dual speed coaster hub? And what's your setup and why you like it done that way.
I'm currently torn between the Sturmey-Archer B2C kickback and the SRAM A2 Automatix. I know that the SRAM A2 is 130mm, but I heard somewhere that it is actually 120mm with 2 5mm spacers?
Thanks again for your kind thoughts and suggestions!
