Now that the ZEB has taken over the enduro category, RockShox updated the all-mountain Lyrik with a new chassis that saves weight without sacrificing strength. The revised DebonAir spring sees increased air volume, giving us added support to keep the fork higher in its travel. The fork is also compatible with RockShox's Pressure Relief Valve kit (not included), which lets us equalize the air pressure in the lowers to compensate for changes in altitude or temperature.
