Is this compatible?

Is this compatible with a "Thorn 104/64 PCD Triple Crankset MK2 - Black" (SJS Cycles part number : 31813l170)?
If it is what would be the chainline if I just used only this chainring? (Would it be 54mm as that's the one I'm looking for for my Rohloff upgrade with the 110mm BB as described in the specifications for Thorn Cranks? )

Best Regards,
Yes you could use this, but we would recommend SJS Cycles part number : 11054S32 as it is designed as a single chainring. The TA is designed for 8/9 speed shifting and have two pairs of shortened teeth to assist down-shifting.

You should get the appropriate chainline if fitted to the outer position.
