Hi people, I`m having a Truvativ Holzfeller Cranks 104mm 2009 model with single 36 tooth chainring, my question is it possible to have a chainring with 22 tooth for 104mm cranks, and who makes such. I found a Truvativ Holzfeller Trials Cranks with 22 tooth but i don`t want to buy a new cranks just a chainring if it`s possible. Thank You.
