For 2025, RockShox has rebuilt it’s lineup of entry -evel mountain bike forks with a simplified model range, a new damper called Isolator, and an updated Debonair air spring. The gravel crowd hasn’t been forgotten, with and updated Rudy gravel fork and Charger Race Day 2 damper.
Rockshox has previously offered multiple entry-level, trail-focused MTB forks. Riders could choose from the Revelation, 35, Yari, and the bigger hitting Domain. There will now just be two different forks; an updated Domain, and the brand has resurrected the Psylo, covering 130mm travel up to 180mm. But before we dive into the boingers, let’s take a look at the internals they are built around.
The all-new Isolator Damper
So, what makes the Isolator different from the previous entry-level damper available from Rockshox? The all-new damper utilises a shim-based, spring-backed Internal Floating Piston (IFP) damper and claims to give riders a consistent and predictable feel throughout its entire range of travel.
The Isolater’s three-position Compression adjustment (Open, Pedal, and Firm) is designed so that when the Isolater damper is Open, oil flows freely through it to absorb big hits. The Pedal setting is supportive without harshness on successive impacts, and Firm offers the maximum damping force to calm bobbing for the most efficient ride.
The good news for home mechanics is that a service kit will be available for the new damper, and no new proprietary tools will be needed. The isolator damper will also be available as an upgrade for the Domain Gold R fork, which will be available as an OEM product only.
Rockshox has not just been busy developing these new forks and dampers, they have also revised the service kits available to consumers. The service kit range has been overhauled and the number of options drastically reduced, there will now be around 35 service kits available down from over 100. The goal of the overhaul is to simplify the ordering and supply process for customers and suppliers.
Debonair gets an update
Rockshox has also updated its popular Debonair air spring to complement the new damper. The updated Debonair spring claims to offer a buttery-smooth, off-the-top feel, tuned to complement the all-new Isolator damper.
With a design philosophy based on the Signature Series’ DebonAir+ air springs, they claim to have found the ideal blend of positive and negative volumes for a taller ride height and increased mid-stroke support to keep confidence high.
Like all Rockshox’s other air forks, the air spring can be tuned by installing or removing tokens. Both new forks will use the existing grey tokens available from Rockshox.
Level Up with the all-new Psylo
The Psylo first appeared in the RockShox lineup in the early 2000s and was discontinued in 2005. Two decades later, it’s back, and the new Psylo replaces the Revelation, Yari, and 35. It’s based on the Pike and Lyric forks and features a 35mm chassis, the new Isolator damper, and an updated DebonAir air spring.
To go with the new chassis, Rockshox has also added premium bushings, claiming to offer lower breakaway force to improve the ride characteristics. It will come in four different travel options from 130mm-160mm and be available for both 27.5in and 29in wheels.
The Psylo is not only designed for your standard trail bikes, it is also E-MTB ready. Just like the current Pike and Lyric, the Psylo utilises Maxima Plush Dynamic Suspension Lube and damping fluid.
Priced at $995 AUD ,the new Psylo Gold RC is about $300-450 AUD cheaper than the Pike and Lyrik, and is expected to be available around late June/ early July in Australia. There will be two lower-spec models of the Psylo — the Psylo Silver RC and Psylo Silver R — that miss out on the new damper and air spring; however these models won’t be available aftermarket and will only come on select OEM builds.

The hard-charging Domain gets an update
Based on the Zeb, the big-hitting Domain fork remains in the lineup as the long travel, hard-hitting enduro offering at a smaller price.
For 2025 it still has a 38mm chassis and a travel range from 150mm up to 180mm but has been updated to accommodate the new damper and air spring. The new Isolator damper found in both the Psylo and the new Domain has 16 clicks of rebound and a three-position compression adjustment.
The Domain will be available for 27.5in and 29in wheels, and like the Psylo is E-MTB ready.
Set to cost $925 AUD, you’ll save about $600 AUD compared to the Zeb, and the new Domain will be available around late June/ early July in Australia. A lower-spec Domain R will be available on some OEM builds. This version will miss out on the new damper and air spring; however if it comes on the front of a complete bike, it can be upgraded to the new damper if purchased separately. The new damper is not compatible with older Domain forks, as the chassis has been updated to accommodate the new internals.
