Not really. RS Lyrik 150mm is 561mm axle to crown, Fox 36 150 is 557mm. So that 4mm difference has maybe a 1mm impact on BB height.I think BB height will also be affected by which fork is specced .. Fox forks normally have up to 10mm more in axle to crown than comparable rs ones. Like fox 36 to lyric. 10mm upfront is like 4mm difference in BB height
