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.

I did and found that I had to add a link. i've been running a chain with two quicklinks for over a year and it's been fine.

That just depends on how close you were before you added the 52. I’ve got bikes it works great on, on others I had to add a link. I’ve got one I can change between 42 and 50 (hardtail).

I reinstalled the old chain and it seems okay. I'll probably give it an extra link on the resizing and go from there.
