i believe it's a 31.8 top pull but check the SC website to be sure.

that's right, but just make sure it's a low-clamp. e.g. the sram x-gen doesn't work as the clamp interferes with the elevated chainstay.

31.8 M760 in Shimano - not sure what SRAM products work.

Top pull, top swing (low clamp)

The SRAM derailuer will not work.
