Rockshox 29-inch MTB fork Rockshox Sid Ultimate Race Day 2 DebonAir+ 3P Flight Attendant

The RockShox SID Ultimate Flight Attendant fork is a beefed-up version of the SID SL, offering identical performance with greater versatility on rough and challenging trails. This version features 35 mm stanchions and 120 mm travel for 29-inch mountain bikes, offering a rigid frame and enhanced capabilities for cross-country and XC downhill riding.

It incorporates innovative electronic technology that automatically adjusts the compression mode (Open, Pedal, Lock). The Flight Attendant system is based on a new algorithm that uses a series of sensors to analyse the rider’s effort and the terrain, and anticipate the ideal suspension setting. As you ride, the system learns your riding style, allowing it to adapt perfectly to your preferences; before you even have a chance to manually engage the lockout, Flight Attendant will have done it for you! An impressive technology that will quickly become indispensable. Featuring wireless AXS technology, the Flight Attendant system integrates with the SRAM AXS ecosystem; the more AXS components you add, the better the Flight Attendant system will perform. Finally, the system boasts IPX7 water resistance, allowing you to ride with confidence whatever the weather conditions.

Still featuring a Boost Maxle Stealth axle, it is fitted with the Charger Race Day 2 cartridge, which is lighter and offers an "Open, Pedal, Lock" compression setting to adapt to the demands of different trails. Low-friction seals, combined with Maxima Pulsh fork oil, ensure quiet and ultra-smooth operation.
The markings on the stanchion make adjustments easy thanks to precise SAG. The DebonAir+ air spring ensures progressive and responsive operation to deliver top-of-the-range damping performance. The specific dimensions of the SID Ultimate fork allow it to accommodate tyres up to 66 mm wide and a 220 mm brake disc (minimum 180 mm).

As you can see, this is a revolutionary XC fork combining lightness, stiffness and efficiency, ideal for serious cross-country riding.
