For 2020, SR Suntour has updated their Durolux fork with features to bring it in line with the offerings from the other suspension giants while coming in at more affordable pricepoint.
The Durolux is aimed at the harder hitting side of trail bikes through enduro to a bit of freeride and is also suitable for e-bikes.

The Durolux was developed in parallel with the Rux DH fork and uses 36mm diameter stanchions with stiffness and durability in mind while still having smart manufacturing details to either drop weight, with the hollow forged crown, or speed up wheel fitment and removal, with their specific QLOC axle. Once used for a few times that axle becomes incredibly quick to take in and out without the need for any tools.
Quick service ports on the back of the cast magnesium lowers allow the release of any trapped air and also make it easy to keep the lower legs lubricated with 15WT oil, although it's advised to never have more than 5cc of oil in each leg, which isn't much at all. These ports require the use of a 2.5mm allen key.
A bolt on fender is also available that extends both front and rear of the arch and looks to do a good job of covering the wiper seals too. Brake mounts are directly for 180mm rotors with a maximum of 203mm possible.
EQ is SR Suntours new air negative spring system. Nothing revolutionary, but now a good feature that SR Suntour are adopting. Positive and negative air chambers are connected via a small transfer port in the inner stanchion wall that allows air to travel between the two as the fork moves through the travel. No need for a physical metal coil to act as the negative spring, meaning the system self equalizes and riders of all weights and setups can have a better working fork.
Air spring volume can be adjusted with spacers to achieve the desired ramp characteristics. In the case of the 170mm travel version, air spring bottom out force can be increased by around 255% from zero to the max of six volume spacers, along with increases in spring force all along the spring curve.
The damper is available in R2C2, RC2 and RC versions, all using SR Suntour's Piston Compensator System. For the R2C2 cartridge in the top fork adjustable high and low speed compression and rebound are on offer. The high speed adjustment has 5 and 4 settings for the compression and rebound respectively. The low speed adjusters have more clicks for tuning with 18 and 28 available for the compression and rebound.
Forks are available in gloss and matt black and gloss white and in both 29" and 27.5" options with varying offsets and travels. Compared to the RockShox Lyrik and Fox 36 the Durolux comes in at 9mm longer axle to crown.
