Featherweight SID SL Select 3 Position fork with DebonAir+ and 3-mode Charger damper
What Our Gearhead® Experts Are Saying:
"I built my race rig around this fork and haven’t looked back. It’s one of the lightest setups I’ve used without compromising on ride quality. The DebonAir+ keeps things smooth over chatter, and I can instantly flip between Open, Pedal, or Lock with the Charger RL damper depending on the climb or descent. It’s perfectly tuned for hard, fast XC days."
The SRAM SID SL Select 3 Position is engineered for cross-country purists who demand the highest level of efficiency, control, and weight savings. Optimized around a 32mm chassis and designed to pair with 29-inch wheels, the fork offers either 100mm or 110mm of travel, giving riders a balanced feel for modern race courses without overcomplicating their cockpit. Its lightweight build—anchored by a forged hollow aluminum crown and magnesium lowers—delivers snappy handling and a planted ride feel across undulating terrain.
At the heart of the SID SL Select is the Charger RL damper with three on-the-fly modes: Open, Pedal, and Lock. This lets racers transition seamlessly from steep climbs to rock-strewn descents while maintaining efficient energy transfer. The DebonAir+ spring system features updated negative air volume and reduced friction, ensuring supple small-bump absorption with plenty of mid-stroke support. A key upgrade is the increased bushing overlap, which boosts stiffness and longevity, even under aggressive XC race loads.
With BOOST 15x110 spacing, 44mm offset, and compatibility with rotors up to 200mm, this fork integrates effortlessly with today’s XC frames and components. We reach for the SID SL Select when we're chasing podiums or personal bests—it’s lightweight, highly tuneable, and race-proven from start gate to finish line.
