Crank Ring sizes?
I know that crank rings have gone from 3x and 2x to 1x (one by) and larger teeth counts like higher 50s to now higher 20s but are there different teeth widths than 1/8 and 3/32 like chains?
Curious since some rings are now termed 11 and 12 speed so was not sure if the widths have decreased from 3/32?
This question is based on SRAM NX crankset where each tooth's thickness is CNC machined to work seamlessly with the chain's inner and outer links making it a better 11/12 spd crank. This CNC machining must change the 3/32 width? Also these rings are only offered in 28T, 30T, 32T, 36T sizes.
