2014 Action Tec 39 tooth 1x9 or 2x9 heat treated ti cog

I have two of these. The one pictured is brand new (SOLD), the other one not pictured is used but has never been run with a stretched chain and is in excellent condition. I had this set up as a 2x9 using an 11-34 cassette. You lose the 11 tooth with this setup, you simply put a 12 tooth 1st position in place of the 11 tooth. If you so desire you could also keep the 11 tooth by removing the 15-17 cogs and replacing it with a 16 cog. A strong rider could certainly do well with this set up as a 1x9 as well.
