For the money, the level of adjustment on this fork is amazing but there are a couple of niggles.
The Durolux is a brand new fork from SunTour. It’s the heaviest fork on test, and the tallest too, but its 36mm stanchions and 20mm axle give the stance of a proper all-mountain fork.
It gets a tapered steerer, hollow-forged crown and magnesium lowers with a post-mount 180 disc mount.
Also in the box is a plastic mudguard, which bolts on the back of the brace using four screws. It’s a good size and doesn’t scuff the lowers or rattle like some aftermarket guards.
You’ll also notice two additional 2.5mm Allen key bolts in this area — these allow you to directly lube the seals and also release any air that’s built up in the lowers.
Tying the lower legs together is a 20mm quick-release axle, called 20 Q-Loc. There’s a knack to removing this — the idea is to twist the red nut so it aligns with the axle and then you pull the whole thing through the hub.
Unfortunately, the nut doesn’t always stay in place, especially if it gets dirty, and it can come undone halfway through and jam.
With its positive air spring and coil negative the fork moves easily off the top. It also comes standard with volume reducers, which are identical to the IVA system used in the Manitou Mattoc. There are three included, but they do have a big effect on the progression — we only ran one.
Surprisingly for a budget fork, the Durolux has a full complement of damping adjustment — high and low-speed compression and high and low-speed rebound.
Smashing down big, lumpy terrain the Durolux never got out of shape and remained totally composed. Trying to find grip on slippery surfaces wasn’t so impressive though — it feels over-damped and propped up.
We thought this might be because it hadn’t bedded in, but we’ve lubed the seals and hammered out a ton of runs, and it’s no smoother.
For the money, the level of adjustment on this fork is amazing; unfortunately, there are a couple of niggles.
It’s noisy, you can hear a sort of squelch coming from the rebound circuit and a rattle on the spring side. Play also developed in the bushings by the end of the test period.
The deal breaker is probably the Q-Loc axle — it’s truly annoying. A standard bolt-thru axle would have been much better than this heavily flawed quick-release system.
