It was a 4-speed version, but I plead guilty to applying it to a 1/8" chain and correspondingly wider-spaced cog block. (This was very common on the 3-speed-to-hybrid conversions. I saw 1/8" chains used on the much more common 13-19-25 9-speed conversions, as well as my own 14-16-18-20 12-speed conversion.) That might have pushed it just a bit too far. All I know is that the Gran Sport worked perfectly in this application.
