RockShox has been at the forefront of mountain bike suspension forks since the early days of mountain biking, releasing the first telescopic fork, the RS-1, in 1991.
Since then, the brand has come to dominate the market, alongside Fox suspension forks.
In this article, we take a look at all the mountain bike forks in the RockShox stable, explaining the technology and intended use case that sets them apart.
RockShox suspension forks
The RockShox mountain bike suspension fork range covers every mountain biker’s needs.
There are 15 models in its range, offering everything from triple-clamp downhill forks with 200mm of suspension travel to super-light forks designed for cross-country racing.
RockShox ZEB
- Intended use: Enduro
- Travel: 150, 160, 170, 180 or 190mm
- Wheel sizes: 27.5 or 29in
The RockShox ZEB is the brand’s flagship enduro fork. Built around stiff 38mm stanchions, it's aimed at riders and racers who need maximum stiffness and travel from a single-crown package.
Sitting at the top of the range is the ZEB Ultimate, often found on some of the best enduro bikes on the market. Specced with a DebonAir air spring and the new Charger 3 RC2 damper, this fork also benefits from RockShox’s ButterCup technology, and premium SKF wiper seals and Maxima Plush damper fluid.
The ZEB Ultimate also features Pressure Relief Valves on the fork lowers. Rounding out this flagship package is a machined and anodised crown for durability and weight reduction.
The ZEB Select shares many features with the flagship ZEB, including the DebonAir air spring, Charger 3 RC2 damper and Pressure Relief Valves, but it misses out on the vibration-damping ButterCups and machined crown.
The ZEB Select is specced with a DebonAir air spring and the more basic Charger RC damper. The rest of the technology is carried over from the Select model, apart from the Pressure Relief Valves, which can be retrofitted if desired.
The entry-level ZEB shares the same DebonAir air spring as its higher-end counterparts. However, it gets RockShox’s new entry-level Rush RC damper for easy low-speed compression and rebound adjustability. The rest of the internals are borrowed from the ZEB Select.
RockShox Lyrik
- Intended use: Trail
- Travel: 140, 150 or 160mm
- Wheel sizes: 27.5 or 29in
The Lyrik is RockShox’s most versatile fork. With 35mm stanchions, it is aimed at mountain bikers who want to be equipped to ride a variety of trails.
The top-of-the-range Lyrik Ultimate gets all the bells and whistles. It’s equipped with a DebonAir air spring and Charger 3 RC2 damper, making it a popular choice for some of the best trail bikes.
Much like the ZEB, it also boasts ButterCup technology, Pressure Relief Valves, premium SKF seals and Maxima Plush damper fluid, as well as a machined and anodised crown.
The Lyrik Select also gets most of RockShox’s top-of-the-line technology, such as the DebonAir air spring and Charger 3 RC2 damper. While it also benefits from Pressure Relief Valves and premium seals and damper fluid, it misses out on the ButterCups and machined crown.
The Lyrik Select has a DebonAir air spring, but not the premium Charger 3 RC2 damper, instead getting the more basic Charger RC with low-speed compression and rebound adjustment. It also lacks Pressure Relief Valves, but these can be retrofitted.
In its most basic guise, the Lyrik relies on a DebonAir air spring and entry-level Rush RC damper. The internal seals and damper fluid are shared with the rest of the line-up and you can also upgrade to Pressure Relief Valves.
RockShox Pike
- Intended use: Trail and downcountry
- Travel: 120, 130 or 140mm
- Wheel sizes: 26 (Pike DJ), 27.5 or 29in
The RockShox Pike is all about trail and downcountry riding. While it has the same 35mm stanchion diameter as the Lyrik, the Pike features a slimmed-down chassis to save weight.
The Pike Ultimate is packed full of flagship RockShox technology. Like the ZEB and Lyrik Ultimate, it features a DebonAir air spring, Charger 3 RC2 damper, Pressure Relief Valves and ButterCups. Premium SKF seals, Maxima damper fluid and a machined and anodised crown complete the package.
The Pike Select is treated to almost all the same technology as the Pike Ultimate, but misses out on the ButterCups and the machined crown.
The Pike Select gets a more basic Charger RC damper, with easy-to-adjust low-speed compression and rebound. Apart from the Pressure Relief Valves, which can be retrofitted, the Pike Select shares the same DebonAir air spring, seals and damper fluid as the rest of the Pike line-up.
RockShox’s entry-level trail fork, the Pike, shares the same Rush RC damper as the other base models in the signature trail and enduro range. It also has the same internal seals and damper fluid. Pressure Relief Valves are available as a retrofittable upgrade.
Designed specifically for use on dirt jump and slopestyle bikes, the Pike DJ features a custom-tuned Charger damper and Solo Air air spring designed to offer maximum progression for harsh landings and heavy compressions.
The Pike DJ is available with 100 or 140mm of travel and is exclusive to 26in wheels.
RockShox BoXXer
- Intended use: Downhill racing
- Travel: 200mm (Spring travel kits available to reduce travel to 180 or 190mm)
- Wheel sizes: 27.5 or 29in
The RockShox BoXXer is a dual-crown fork designed for downhill racers with 38mm stanchions.
The BoXXer Ultimate is the flagship model. It has a Charger 3 RC2 damper and a downhill-tuned DebonAir air spring with ButterCups. It uses SKF wiper seals and Maxima Plush damper fluid.
The BoXXer uses the same chassis and downhill-tuned DebonAir air spring as its flagship counterpart but forgoes the ButterCups. It relies on a Charger 3 RC damper and uses Maxima Plush damper fluid.
RockShox SID
- Intended use: Cross-country
- Travel: 110 or 120mm
- Wheel sizes: 29in
The SID is RockShox’s flagship cross-country fork. It’s a light but stiff suspension fork for racing or setting hot laps on the local cross-country course. The SID is built with 35mm stanchions and is available for use only with 29in wheels.
The top-end SID Ultimate features RockShox’s new Charger Race Day 2 damper, designed to be as light as possible, while offering three damping modes to choose between. The DebonAir air spring has also been revamped with increased positive and negative air volumes. A new machined crown, SKF wiper seals and a new proprietary blend of Maxima Plush damper fluid add the final touches.
The SID Select shares the same DebonAir air spring as the SID Ultimate and gets the same Charger Race Day 2 damper but without the same machining. Other than that, it shares its seals and damper fluid with the flagship model.
The SID Select steps down to a Charger XC damper but retains the DebonAir air spring.
The entry-level SID features the same DebonAir air spring, and SKF and Maxima internals, paired with the basic Rush XC damper.
RockShox SID SL
- Intended use: Cross-country
- Travel: 100mm or 110mm
- Wheel sizes: 29in
Designed for cross-country racers looking for the lightest fork available, the RockShox SID SL uses 32mm stanchions and specially machined lowers to shave as much weight as possible. Unlike the SID, the SID SL doesn't use the new DebonAir air spring.
Four models are available (the SID SL Ultimate, SID SL Select , SID SL Select and SID SL), which share the same internals as the RockShox SID forks.
RockShox Domain

RockShox suspension fork technology
Dampers
The Charger 3 is the latest RockShox damper, offering low- and high-speed compression adjustment, as well as rebound in its RC2 guise. The Charger 3 damper is available in the Ultimate and Select versions of the ZEB, Lyrik and Pike suspension forks.
The previous-generation Charger 2.1 damper is still in use on multiple forks in the RockShox line-up, such as the BoXXer Ultimate.
The damper comes in two configurations. The Charger 2.1 RC2 has low/high-speed compression and rebound adjustment, while the Charger 2.1 RCT3 has a three-position compression lever (open, pedal, lock) and rebound adjustment.
The Charger 2 is the predecessor of the Charger 2.1 and features the same RC2 and RCT3 configurations, as well as an RC option that offers adjustable low-speed compression and rebound.
The Isolator is the latest damper from RockShox. It features a new internal floating-piston design and its rebound piston uses a dual-flow rebound circuit similar to the Charger 3 damper. The Isolator is available with a three-position compression dial.
There are a number of dampers used on entry-to-mid-level RockShox forks. These include the older Motion Control, seen on forks such as the Yari and Revelation, and the newer Rush damper found on forks such as the entry-level Pike, Lyrik and ZEB.
RockShox damper adjustment names
RockShox has several names to explain the adjustments a damper system allows, which are outlined in the chart below.
| Name | Adjustments |
|---|---|
| RC2 | Low/high-speed compression and rebound |
| RC | Low-speed compression and rebound |
| RCT3 | 3-position compression (open, pedal, lock) and rebound |
| RL/TK | 2-position compression (open, lock) and rebound |
| R | Rebound-only |
ButterCups
RockShox ButterCups are rubber isolators that sit at the bottom of the spring and damper shafts of the Ultimate versions of BoXXer, ZEB, Lyrik and Pike forks.
According to RockShox, the ButterCups reduced trail chatter by 20 per cent in its in-house tests. This should translate to reduced fatigue in the hands and arms on rough descents.
ButterCups are retrofittable and included in Charger 3 and DebonAir upgrade kits.
DebonAir spring
The DebonAir is RockShox’s latest air spring and is seen on 2023 ZEB, Lyrik and Pike models and the 2024 SID and BoXXer.
Although the design is similar to its predecessor, the new DebonAir has a larger negative chamber and a tweaked equalisation design to improve sensitivity and mid-stroke support.
DebonAir spring
The RockShox DebonAir spring is the predecessor of the DebonAir and tuned versions are used across a wide range of models, such as the SID SL.
SoloAir spring
The SoloAir spring is RockShox’s basic air spring and is found on forks such as the RockShox Reba and 35.
Pressure Release Valves
RockShox’s Pressure Release Valves are small valves found on the back of the fork lowers, just under the seals. These enable the release of unwanted pressure build-up in the fork lowers, caused by changes in altitude or temperature.
Flight Attendant
RockShox Flight Attendant is an electronic suspension adjustment system that optimises your suspension damping on the fly using sensors in the forks, shock and cranks. The system also enables you to manually adjust compression modes using SRAM’s AXS shifters.
It is found on Ultimate Flight Attendant models of the ZEB, Lyrik and Pike models, and you can fit it into non-equipped models of the same forks.
