I hope someone with actual parts can help me determine if I have PG-850 or a PG-830 cassette? I made a weak attempt to search this forum. I also checked out the SRAM website and the only difference I can glean from SRAM 2008 Tech Manual is the weight (280g vs. 320g respectively) and the material for the cogs (SAPH 440 Steel vs.Steel respectively). I have access to digital scale, but I doubt it is accurate enough given part and scale tolerances. As for material, no clue. Is there something stamped on the part itself or a distinguishing feature? Any information or comments are welcome.
Thanks for your help and get out and grind some gear(s) today!
