I am thinking of going up a tooth or two on my fixed rear cog and am wondering what all the numbers/letters on my existing one are and are they relevant?
They read BC1.37 x 24TPI 1/8" - 16T
Now I get the 1/8" (width of tooth) and the 16T (no. of teeth) but what are the others? TPI on saw blades means teeth per inch, but that can't be right, surely?
Thanks
