RockShox Announce 2024 SID XC Forks and SIDLuxe Shocks with New Everything

RockShox has updated its entire range of XC-focused suspension with the release of the 2024 SID and SID SL forks, and SIDLuxe shocks. Lighter components are combined with more supportive and more durable internals, with increased on-the-fly adjustability thanks to new 3-position compression adjustment available throughout the entire lineup.

The 2024 RockShox SID Ultimate weighs a claimed 1,480g in its 120mm travel configuration; that’s 57 grams lighter than the predecessor, but still a way off the 1,405g claimed weight of the Intend Samurai CC. Thus, it does not reclaim the title as the world’s lightest 120mm fork, for anyone counting. The 2024 SID SL in its 100mm configuration is just 7 grams lighter than its predecessor, at 1,326g. It is the world’s lightest 100mm travel fork.

With weights out of the way (for now), let’s check out the newness inside RockShox’s latest and greatest cross-country suspension components.

2024 RockShox SID XC Forks with DebonAir+ Spring

The new RockShox SID retains its 35mm stanchion diameter, now built around a refined chassis that we’ve seen in use throughout this season of XCO racing. That would be the RockShox SID Ultimate that has been floating about on the World Cup circuit, it’s reduced weight being one of numerous improvements.

Of course, weight isn’t everything. Cross-country race courses are seeing increasingly technical descents year-on-year; speaking of which, riders are in for a surprise with some seriously enduro-worthy features lying in store at the 2023 UCI World Championships in just under three weeks’ time.

With that in mind, RockShox has looked to boost performance with a new, higher volume DebonAir+ air spring with improved mid-stroke support, and increased suppleness off the top of the stroke. All four 2024 SID forks benefit from the new air spring. To name them; SID, SID Select, SID Select+, and SID Ultimate (below, in that order from left to right). All are available in 29″ only, with a 44mm offset. Only the Ultimate fork gets the heavily-machined crown and Blue Crush lowers.

As compared to the DebonAir spring of the previous model, the DebonAir+ has a 50% larger negative air volume, and a 16% larger positive air volume. For ramp and bottom-out control, the air spring takes the usual bottomless tokens. At top-out, a coil spring replaces a rubber bumper for improved hysteresis.

Before you get too excited, the DebonAir+ air spring is not backwards compatible with previous RockShox SID and SID SL models.

The higher volume air spring required use of longer stanchions; 25mm longer, to be exact. Taking advantage of that, RockShox has been able to increase bushing overlap by 5%, resulting in 50% more bushing surface engagement. That update reduces sliding friction as the stanchions telescope through the lowers, particularly when the fork is loaded side-on. This, combined with the use of a new, higher viscosity Maxima Plush Dynamic Suspension Lube that is also in use on the 2024 BoXXer DH fork, is said to increase the longevity of the fork’s internals. Nevertheless, recommended service intervals remain unchanged.

On the damper side, we see the introduction of the Charger Race Day 2 cartridge, said to be RockShox’s lightest performance driven damper ever. There is a 2-Position compression adjustment option, as well as a new 3-Position adjustment boasting a “Pedal” position alongside the usual “Open” and “Lock” positions. The 2024 RockShox SIDLuxe shock gets the same 3 Position compression adjustment option, with a new TwistLoc Ultimate remote that allows the fork and shock settings to be adjusted in unison. More on those later.

That new Pedal position is said to combine watt-friendly efficiency with comfort, traction, and control to make quick work of dicey climbs or fast, flowy singletrack.

On top of its improved on-the-fly adjustability, the Charger RD2 damper gets more machining than the original Race Day damper, reducing weight (no actual weight given). Only the SID Ultimate and SID Select+ models get the RD2; the SID Select and OEM-only SID get the Charger XC and Rush XC dampers, respectively, said to have an equivalent performance but in a less intricately-machined, heavier package.

The Charger Race Day 2 damper is backwards compatible with the previous iteration of the RockShox SID and SID SL forks. Those looking to upgrade will need to part with $269 USD / 319 € / £289 for the pleasure of either the 2- or 3-Position compression adjustment.

2024 RockShox SID SL

The RockShox SID SL sees fewer updates for 2024. As the lightest fork in the range, it holds onto 32mm stanchions but rather notably there are now two travel options; 100mm and 110mm. The 100mm SID SL Ultimate weighs a claimed 1,326g, while the 110mm travel option comes in at 1,352g. The SID SL Ultimate is the only one to benefit from the Blue Crush lowers and the machined crown.

The SL fork runs on the DebonAir spring utilized by previous models; on this, we are told that SRAM’s sponsored riders are happy with the current offering. It does however benefit from the lighter Charger RD2 damper, with both 2- and 3-Position compression adjustment available. Minimum and maximum brake rotor size is 160mm and 200mm, respectively.

What about Flight Attendant?

In June of this year, we saw Nino Schurter take his 34th World Cup win in Lenzerheide aboard his Flight Attendant equipped RockShox SID (we also saw a pile of new XC suspension, brakes and tires). While we’ve seen this automatic, electronically adjustable suspension system implemented on production trail and enduro bikes, it remains to be seen whether the cross-country segment will also benefit.

2024 RockShox SIDLuxe XC Shocks

Like the 2024 SID and SID SL forks, the new SIDLuxe shocks also benefit from a 3-Position compression adjustment. It retains the rock solid “Lock” position, and the “Open” position for fully active compression and return, with the addition of the “Pedal” position in the middle said to perfectly blend traction and efficiency for technical climbs and undulating trails.

Also new for 2024 is the addition of a more responsive blow-off mechanism for the high speed compression in the Open and Pedal modes. To allow for that, RockShox has increased the oil flow through the damper. As a consequence, the engineers had to improve bottom-out control with the introduction of a taller, tapered bottom-out bumper to reduce harshness at the end of the stroke.

New bottomless tokens are available for the 2024 SIDLuxe to give riders more control over end-stroke ramp; these are not the same as those used for the previous SIDLuxe models, with a new shape designed to fit an updated seal head and piston.

Unfortunately, older models of the SIDLuxe cannot be upgraded to the 3-Position compression adjustment. However, if you buy a new bike that comes with the 2024 SIDLuxe with a lever, you can upgrade to the 2- or 2-Position remote with an aftermarket kit retailing at $54 USD / 64 € / £59.

There will be just two SIDLuxe models. The lightest, top-end offering is the SIDLuxe Ultimate, sold with the option to run those eye-catching Blue Crush decals or the more stealthy black ones. It is the only one available aftermarket, with MSRPs ranging from $439-509, 539-609€, £479-539. This top-end shock weighs 246 grams in the 190mm x 45mm option with standard body eyelet.

The SIDLuxe Select+ is equivalent to the SIDLuxe Ultimate on every point save for weight. Oh, and you can only get it with the black decals.

Model-Specific SIDLuxe Shocks

The new SIDLuxe is available with the choice of two air cans; DebonAir and SoloAir for a comparatively more progressive, or more linear spring curve, respectively. RockShox has worked with a number of frame manufacturers to develop kinematic-specific damper tunes for the 2024 SIDLuxe shock. Bikes on that list include, but are not limited to:

• BMC Fourstroke (2021+)
• Mondraker F-Podium DC (2022+)
• Santa Cruz Blur TR (2022+)
• Transition Spur (2020+)
• Canyon Lux TR (2022+)
• Santa Cruz Blur (2022+)
• Specialized Epic Evo (2021+)
• Trek TopFuel 2020-2022
• Mondraker F-Podium (2020+)

New TwistLoc Ultimate Remote

RockShox has also updated the TwistLoc Ultimate remote in line with the advent of the 3-Position adjustment on the new SID, SID SL and SIDLuxe suspension components. It is available with a textured rubber grip, or with a lighter, smoother slide-on grip made of foam. The collar that integrates the cable-pull mechanism is much narrower than we’ve seen on previous iterations of the TwistLoc remote, creating more space on the bar for better positioning of a dropper remote. Get it for $117 USD / 133 € / £119.
