We’ll be the first to admit it, SR Suntour has not historically been one of our first picks for suspension when putting together a “dream build.” Their large OEM market has traditionally been on lower end big box bikes and the entry level spec of larger name brands. But the pendulum seems to be swinging back the other way thanks to forks like the Auron 29. For those that only think SR Suntour makes cheap forks, the brand actually developed one of the first magnesium-built forks way back in 1995. Since that time, they have continued to quietly innovate in both suspension design and gearbox technology.
While some brands have focused on merely creating expensive, top-shelf products, SR Suntour has remained steadfast in their quest to deliver quality suspension at affordable prices. Don’t let that fool you though. An SR Suntour rider stood on the top step at the 2014 Olympics. They have helped athletes stand on podiums at Red Bull Rampage, North American Enduro Championships and World Cup Downhills.
In typical SR Suntour fashion, without a huge marketing campaign and little in the way of fanfare, they released the Auron fork and TriAir 3CR shock earlier this year. We were lucky enough to get some of their first few units and have been stoked on them ever since.
We were sent the Auron 29 fork in 150mm travel and 110mm Boost spacing. The fork weighs 2171g with the axle thanks to magnesium lowers and a hollow crown. Damping is controlled through the Piston Compensator System (PCS), which is a proprietary floating piston that is said to decrease oil cavitation and provide a more consistent feel. The right fork tube has two adjusters to control both the low and high speed compression circuits. Rather than having to count dozens of clicks, the Auron sports an easy to use adjuster with numbers 1-5.
Rebound adjustment is found on the right lower fork tube and has a very useful range of clicks, with two clicks being a very noticeable change. There are four different levels of spring tuning available for the air chamber, though we found the stock setup to offer a good amount of small bump sensitivity and progression.
Our SR suspension upgrade matched the Auron 29 with a TriAir 3CR. The TriAir, like many other rear shocks has a three position adjustment lever. Depending on your preference for climbing efficiency and platform, you can switch the lever to stiffen the shock. A simple, red rebound adjust knob accurately and easily controls the shock’s return speed. SR Suntour offers the TriAir in several configurations in both metric and Imperial measurements.
Although simple, the system never left us asking for more adjustability. The bushings have an ultra-low friction coating and the supplied hardware bolted up with no problems. Spacers are available for the air can, but again we found no reason to adjust from the stock setup.
SR Suntour’s integrated fender works great and blends nicely into the lines of the arch. We also really liked the axle. The QR system took a minute to understand when we first got it but once we had it down, it was quick to use and trouble free throughout our test.
