This thread is three years old. I don't think the original poster has the bike anymore. I am running the 06SE belt and the 28 tooth with a turbo and I just rolled over 17000 miles on the belt.How has your belt held up? mine has 200km on it and its destroyed. Im running a 07 wheel, pulley, 03 spacers and cushdrive, 06SE skinny belt, 28tooth front pulley. just curious why my belt is showing the braiding so soon.
