JavaScript seems to be disabled in your browser. Spindle diameter is 24mm on the drive side, and 22mm on the non-drive side where the splines are. There is another, more subtle, incompatibility that affects different brands of hubs and wheels, but it will only have an impact on those riders using multiple wheelsets. NOTE: FSA MegaEXO crank spindle diameters can be as large as 24.07mm. This is not something crank manufacturers recommend, though, with some pointing to a difference in the spacing of the chainrings as a potential problem, however the weight of anecdotal evidence clearly suggests otherwise. In general, the performance of these combinations may be satisfactory but it is not guaranteed, or there is a risk of an incompatibility, depending on the specific components involved. And while it is preferable to match the chainrings/crankset to the transmission, there is no strict need to do so. The SRAM NX cassette specification is 11-50T, calculating to a range of 454%. SRAM. In its press release, it claims that the RaceFace Next SL G4 crank (arguably the XC market leader), with the equivalent length, ring and bottom bracket is 518 grams. Therefore, you need to compare specific rotational bits of the NX and GX drivetrains to know if that 15% weight difference is universal. Once again, shims can be used to normalise the alignment of the rotors for multiple wheelsets, but this is only possible for 6-bolt rotors, so those using centre lock hubs may have to consider a switch to a 6-bolt adapter.

The SRAM XD freehub body (or driver) is a stubby structure that is distinct from Shimanos and Campagnolos freehub designs. So while the NX offers good enough strength for its price, it is not as stiff as the GX, which offers better strength to weight ratio. It is one of the press fit BB standards. Thats because there is generally very little interchangeability between groupset components, but there are some exceptions. Would e.g. SRAMs GXP is a 24mm spindle that tapers to 22mm on the left crank. While ideas such as Boost width hubs require frame manufacturers to re-design the back-end of their frames, save for Super Boost and Cannondales BB30Ai BB shells, SRAM reckons it has a bottom bracket to suit every frame. As noted above, there is little or no backwards or forwards compatibility for Shimano, Campagnolo, or SRAM, so earlier versions of any given shifter may not be compatible with current derailleurs (and vice versa).
