SR Suntour Durolux 38 Spreads Out w/ New Chassis & Damper
Apr
The SR Suntour Durolux 38 strikes their burliest single-crown fork squarely into the realm of enduro and all-mountain. An even 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 prime 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 general width. The “Leg Middle” distance will increase from 145mm to 151mm distance, which suggests they mainly 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 normal 110mm Enhance spacing.
It will get a brand new RC+ damper that’s been in growth for 4 years and simplifies the exterior controls to low-speed just for each compression and rebound.
At one level, SR Suntour’s prime damper was the R2C2, which supplied 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 nearly the identical spot, no matter rider weight or using model. And as soon as they set it, they hardly ever modified it. So why trouble with the complexity of constructing it adjustable? It’s nonetheless internally adjustable through 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 prime to expel any additional 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 package 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. Obtainable 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 prime 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 internal 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 damaging chamber quantity by share of something they’ve made. That allows you to run larger strain so it has good assist, however continues to be actually compliant on the little stuff. I’ve ridden it and it’s certainly a relatively good gravel fork.
