The SR Suntour Durolux 38 strikes their burliest single-crown fork squarely into the realm of enduro and all-mountain. A much bigger chassis and wider stance give it a commanding presence, plus new “EVO” rear shocks and updates to their Auron and GVX forks spherical out the updates for 2025. There’s additionally an all-new damper on the high finish of their fork vary.
2025 SR Suntour Durolux 38
The Durolux upgraded to 38mm stanchions in 2021, so the large change right here is its total width. The “Leg Middle” distance will increase from 145mm to 151mm distance, which implies they principally spaced the stanchions 6mm additional aside. This made room for bigger lowers giving it a wider stance, beefier physique, and a hair extra tire clearance.
Dropouts are available flush to accommodate that development, sustaining commonplace 110mm Enhance spacing.
It will get a brand new RC+ damper that’s been in improvement for 4 years and simplifies the exterior controls to low-speed just for each compression and rebound.
At one level, SR Suntour’s high damper was the R2C2, which offered exterior management of each high- and low-speed compression and rebound. Then they simplified by eliminating the high-speed rebound, and now they’re simplified it much more.
Why? They are saying most riders would set the high-speed compression to virtually the identical spot, no matter rider weight or using fashion. And as soon as they set it, they not often modified it. So why hassle with the complexity of creating it adjustable? It’s nonetheless internally adjustable by way of the shim stack for riders who actually need one thing completely different.
However wait, there’s extra…
The 2025 Durolux is their first fork with splash lube within the lowers. The damper cartridge has a bleed port on the high to expel any further that it would ingest. A brand new machining course of dramatically improves the tolerances and alignment between higher and decrease bushings. They are saying this reduces friction a lot that the stanchions will simply slide down on their very own when inserted into the lowers (earlier than including the damper and air spring, after all).
The SKF seals carry over, however they add lubrication ports that use a disc brake bleed equipment becoming to connect. It may be had as a Durolux 38 X mannequin with built-in ABS mounts and a stable crown model for heavier e-bikes. In any other case, you get a lighter hole crown and no ABS mounts. Accessible in 160/170/180mm journey, weight TBA.
2025 Auron 36
The SR Suntour Auron bumps as much as 36mm stanchions. That’s a bump from 35mm, which was up from 34, so it’s gone from downcountry to correct all-mountain fork and is available in 150-160mm journey variations. It additionally will get the brand new RC+ damper.
Edge EVO inline shock
The brand new Edge EVO inline shock is their new high of the road XC/Path/AM shock. It has a bigger constructive air chamber that makes it extra tunable with spacers. Internally, a stainless-steel inside shaft and elevated bushing overlap makes it to withstand lateral forces imposed by suspension yokes and hyperlinks.
It is available in two air can quantity choices (proven), with three damping cartridge controls:
- R – exterior rebound solely
- 2CR – exterior rebound plus open/closed compression
- 3CR – exterior rebound plus open/pedal/closed compression
GVX gravel suspension fork
Not new or up to date is the SR SUntour GVX gravel suspension fork. However they wished to level out that it has the biggest unfavourable chamber quantity by share of something they’ve made. That allows you to run increased strain so it has good help, however remains to be actually compliant on the little stuff. I’ve ridden it and it’s certainly a reasonably good gravel fork.
