Long travel trifecta: plush, stiff, and supportive.

From the lift-serviced downhill runs of your local resort to the rocky descents of timed enduro stages, the RockShox Lyrik RCT3 DebonAir (51mm Offset) 29/27.5in Fork has you covered with unflappable levels of stiffness and support, alongside its plush off-the-top feel, which makes easy work of gaining traction over rough bits of loose rock and bumpy roots. Beefed up over its smaller Pike sibling, the Lyrik RCT3 is RockShox's premiere fork for aggressive styles of all-mountain riding and enduro racing. It's been revamped for 2018 with a DebonAir spring and Charger 2 damper improving its overall suppleness, small-bump traction, and mid-stroke support.

As the go-to choice in RockShox's line for long-travel applications and aggressive riding styles, the Lyrik is the stiffest fork this side of a dual-crown Boxxer used exclusively on downhill bikes. The secret to its rock-solid feel lies in 35-millimeter stanchions with thicker walls versus what you'd find with a Pike, meaning it tracks more precisely when you're thrashing the living hell out of this fork and pushing it to the absolute limit of control on downhills with intimidating drops and imposing rocks.

Newly introduced for the 2018 line of Lyriks, the Charger 2 damper improves the fork's small-bump sensitivity, which equates to better traction when you're riding across sections of jarring roots and rocks. The new damper widens the range of low-speed compression tuning, giving you heightened levels of adjustment for perfecting its feel on the trail. It's also easier than ever to turn the lever of the 3-position adjust knob, meaning it now works with OneLoc handlebar remotes.

Another new addition, the DebonAir spring is borrowed from RockShox Deluxe and Super Deluxe shocks. This technology increases the negative air spring volume of the fork, thereby making it more supple off-the-top, as well as increasing its mid-stroke support as you push the bike at higher speeds.

Seeing that it's made exclusively for the newest Boost standards, the Lyrik now clears wide volume trail and plus-sized tires without any issues. This particular version of the Lyrik easily fits 29 x 2.8 and 27.5 x 3.0-inch tires, giving you the ability to run a much lower pressure for better traction and bump compliance. Another design feature inherent to this particular fork, the 51-millimeter offset reduces the "dead space" between the steering axis and hub. This offset negates the slow and sluggish handling inherent to many 29ers with slacker geometries.
