Swapping a Lefty PBR 90 for a Lefty 2.0 (or a Lefty Ocho) isn’t a straight plug-and-play—you’ll need a conversion kit because the newer models use different clamp dimensions, steerer interfaces, and in the case of the Ocho, a different mounting system. It’s also a good time to check and service the precision bearings in your Lefty setup, since smooth and properly adjusted HA597851 bearings are essential for keeping the fork running at its best after the upgrade.
