Boost your confidence.

The RockShox SID RLC Solo Air 100 Boost (51mm Offset) Fork - 29/27.5 Plus boasts race-ready stiffness, speed, and lightweight efficiency with Boost axles for an added dose of confident handling. This SID RLC features a hint of rake to decrease the bike's trail and increase confidence through low-speed finesse sections. It also reduces "dead" space between the hub and the steering axis, which counters the squiggly, low-speed steering issues that often accompany the longer trails produced by tall wheels and slack geometries. Handling stays razor sharp at all speeds, whether climbing, descending, or deftly navigating tricky terrain.

The chassis gets an update this year, reshaped with a focus on gram-saving efficiency. Accordingly, this version of the fork offers the indisputable increase in stiffness and responsiveness of Boost axle spacing. RockShox doesn't divulge specifics of the top-secret design, but claims it adds rigidity across the chassis while saving weight, and the straight-wall aluminum stanchions and magnesium lowers each do their part to add lightness and durability.

Within the suspension, a whole host of RockShox's proprietary technologies work with the SID RLC's 100mm of travel, including its Charger Damper which lends the fork its plush, smooth response as you take it over rock-encrusted singletrack. The aptly named Rapid Recovery design works with the fork's Dig Valve to improve the SID RLC's ability to rebound after successive hits on root-laced climbs and rutted out trail, and the option to add RockShox's Bottomless Tokens to the fork's interior gives you further license to fine-tune the ramp-up and limit your likelihood of bottoming-out.

Finally, the SID RLC's air spring itself, Solo Air, continues to be designed for ease-of-use. It's metered via a Schrader valve that feeds air to both chambers while printed-on Air Guides keep set-up time to a minimum and make sure you don't waste valuable ride time trying to get the suspension set up just right.
