RockShox Sid Ultimate Race Day 2 DebonAir+ 3P 29-inch MTB Fork

The RockShox SID Ultimate 3P fork is a beefed-up version of the SID SL, offering identical performance with greater versatility on difficult and rough trails. This version features 35 mm stanchions and 120 mm travel for 29-inch mountain bikes, offering a stiff frame and enhanced capabilities for cross-country and XC down-country riding. Still featuring a Boost Maxle Stealth axle, it is equipped with the lighter Charger Race Day cartridge, which offers a ‘closed’ compression setting for superior performance on fast sections. This version offers 3 positions: "open", "closed" and "locked", adjustable from the fork crown. Low-friction seals, combined with Maxima Pulsh fork oil, ensure quiet and ultra-smooth operation.

The markings on the stanchion facilitate adjustments 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 an XC fork combining lightness, stiffness and efficiency, ideal for serious cross-country riding.
