Any XC course, any distance: RockShox's SID RCT3 gives you an advantage everywhere. With the flick of a switch, the RCT3 damper changes between full travel, lockout, and threshold modes, ensuring you'll have the best suspension setting no matter the terrain. The whole chassis is light and stiff, while the Solo Air chamber is fully tunable for a custom feel and a dialed ride. Featuring a tapered aluminum steerer, magnesium lowers, and post mount disc brake bosses, the SID RCT3 is truly ready to ride ahead of the pack.

RockShox Maxle Lite
RockShox's Maxle Lite is a lightweight through-axle system. It lets you remove and install your wheel as fast as with a standard quick-release while delivering the awesome stiffness and improved strength and control of a through-axle. Plus, the lever can be closed in whatever position you like and no tools are required for installation and use!

RockShox RCT3 Damper



For the ultimate in cross-country riding characteristics and shock performance, RockShox’s RCT3 damper has open (full-travel) and lockout settings, plus a threshold mode. This is a platform setting that stiffens the initial part of the stroke, helping increase pedaling efficiency. When you hit a bump, the damper opens and allows full travel, then returns to threshold mode once the trail smooths out.
