Hello, friend. I`m using it on my boost Spark `2018 and it`s working well. Rotor crankset is for UBB (universal bottom bracket) and it`s just a spinde - not boost or non-boost. The chainline providing by chainring displacement and it`s working well with this chainring on my Scott Spark boos frame. I also have Spark trail and Scale - it`s going well the same. But there is some addition information you should know: you need a special head to replace your old Rex spirder and install / replace direct mount chainrings. It`s expensive original and cheaper replacements also. Rotor direct mount chainring is stiffer and works longer. Unfortunally the weak part of this set on Scott Spark frame is the 4130 bottom bracket which don`t like mud rain and legpower -) I have three bikes with two rotor Rex on them with DM chainrings and I`m changed the second rex powermeter with quarq on my main bike to be more useful for my large mileage -> chineese cheap and long working dub bb, cheap bcd104 chainrings. Check your budget for all the payments for using it on Spark (chainrings, head, bb) to make a right choice to your regular mileage. I think this crankset is less reliable and more expensive to be used for professional mileage 15+k per year.
