Hey my cassette is worn out and I'm looking to replace it. The stock part on my 2014 REI Novara Buzz is an SRAM PG-830 11-32.
Only ones I'm seeing are PG-820 11-32 and PG-850 11-32. Is PG just the part number or are those incompatible with my bike?
Also are there any Shimano casettes (for example) that I could use as a substitute if I can't find the SRAM part I need?
