The only thing you need to know besides diameter (27.5 duh), freehub body type (standard shimano style or SRAM XD) and rotor mount (6 bolt or center-loc) is rather or not the hubs are "Boost" spec (110 front & 148 rear) or standard thru-axle (100 front & 142 rear). Of course don't do something silly like buy super wide (30mm internal width or wider) rims and your all set to shred that gnar...
