    I have an old SRAM X9 chain set from early 2011 running 24/38T. I’m struggling to find its BCD as I’ve just bought a new X5 chainset being told the chainrings were interchangeable, which they’re not. The new X5 set is 120 BCD. Anyone know what the old X9 BCD would be? It’s not stamped on the chainrings or cranks.
