I had some questions concerning ring size, if you dont know your size,
and dont have a ring sizer, you can google ring size chart. I did measure
the chain rings, and got these measurements. which are approximate. and
are measured on the INSIDE of the ring.
size 6=21/32", 7=11/16, 8=23/32, 9=3/4, 10=13/16, 11=27/32,
12-7/8, 13=29/32, 14=15/16, and size 15=1".
