My Sram GX 50t is pretty much shot, so I just picked up a 52t X01 (still using 50t cassette). The distance between the pulley wheels are the same, I believe its just the offset to allow for the bigger cassette. I was hoping to do a direct swap without pulling the shock (coil) to determine chain length. Has anyone made this swap? I grabbed a new chain but was hoping to measure the old to keep it simple, cause I'm being lazy.
