Answer: 
No; this is a Post-to-IS adaptor. To mount an IS caliper to a Post Mount fork you need an IS-to-Post adaptor. The only such adaptor we stock is the Hope version below, which will require you to increase your rotor size by 20mm as well. Other immediate alternatives would be a new Post-Mount brake caliper, or a complete new brake.

Answer: 
This adaptor is specific to XTR calipers due to the lower profile of the caliper compared to XT/SLX etc.
