Dual xloc bleed5/18/2023 Our sample weighs 1,600g, but that’s with a full-length 265mm steerer tube, 15mm axle, X-Loc remote lockout and RockShox’s 39g expanding headset preload plug. RockShox have shaved a truck load of weight from the chassis with the redesign of the SID and Reba. The new SID isn’t the stiffest 29in cross-country fork out there, but this wasn’t RockShox’s intention rather that intention was to build a fork for 29in wheels that lives up to the Superlight Integrated Design (SID) tag, which this fork seems to admirably. This means larger or more aggressive riders may be better off opting for the alloy CSU SID XX instead, or looking to the new, trail worthy SID 120 or the stouter Revelation 29, which can be chopped down to just 120mm of travel. According to the company’s figures, bending stiffness is eight percent lower and torsional stiffness 15 percent lower (with a 15mm Maxle Lite axle), although a testing tolerance of 10 percent needs to be taken into account. We put this to RockShox’s Jeremiah Boobar, who verified that the carbon World Cup crown/steerer/upper (CSU) assembly isn’t quite as stiff as the alloy version. However, under hard cornering we could feel twist in the legs (transverse plane), accompanied by the sound of rotor rub, on a perfectly adjusted brake. Fore-aft rigidity seemed fine, as well as stiffness in the sheer plane side to side. Given that our test sample was equipped with a 15mm axle, we were expecting the new fork to be stiffer. The Dual Flow rebound is the most noticeable damper performance upgrade to the fork The dual flow rebound damper is the most noticeable damper performance upgrade to the new fork: the dual flow rebound damper is the most noticeable damper performance upgrade to the new fork Matt Pacocha We generally ride on the mid-to-light side of damping setup recommendations the Dual Flow design will provide even greater benefit to those who like a heavier setting, as it allows that heavier initial feel with the ability to more quickly recover from deep-stroke hits. On fast downhills the SID seems to react more quickly and ride slightly higher in its travel. On the rebound side, the damper is upgraded to RockShox’s Dual Flow design and this clearly benefits the fork. We found performance to be almost identical it’s a simple damper that offers good control that’s adequate for the travel category. RockShox say this offers better consistency and damping performance. The XX damper with its X-Loc remote is pretty much the same as last year’s, save for the new DNA spring tube. For this reason, we’d recommend using the negative air chamber and/or damper to adjust the feel of the fork, not the positive chamber. With 20 percent, we found ourselves on the lower end of RockShox’s recommended pressures, even with the spring’s added volume. But getting full travel definitely depends on where you’re setting your sag. The air spring has a higher volume than previous models, and thus offers a slightly less progressive ramp-up.
