SR Suntour’s New Auron 29 and Aion 27.5 forks

27.5 Enduro Forks Sea Otter Classic

SR Suntour Auron fork

The Auron fork from SR Suntour came out last year in 27.5 and is one of their most popular models. It is an All Mountain/Enduro fork with 150 or 160mm of travel and has some great features like a hollow crown, hi-low speed compression adjustment, rebound adjustment, 34mm stanchions and it has Suntour’s lightest thru-axle, the QLOC Ti (titanium skewer). Inside the magnesium monocoque lowers, the Auron has a brand new sealing system, bushings, and adjustable volume for the air chamber.

At the Sea Otter Classic, we talked with Darren Salsbury, the General Manager for SR Suntour about the all new version for this year, the Auron 29. Darren explains, “Suntour’s enduro racers loved the Auron 27.5 so much, we decided to expand the line to include 29ers this year. BMC’s Project Dirt team is running the Suntour Auron 29ers on their TrailFox race bikes. The Auron 29 is made for big, burly riding.” The Auron 29 has all the same features as the Auron 27.5 with similar weight and performance.

SR Suntour Aion fork

Also on display at the Sea Otter, the all new Suntour Aion fork offers very similar performance to the Auron, but at a significant price savings. The Aion is the “little brother” to the Auron and has the same lowers, same sealing system, and same air spring. It has the low speed compression and rebound adjustment, but not the high speed adjustment. The Aion also has a more affordable version of the QLOC thru axle but with steel axles, not ti which, of course, makes the Aion slightly heavier. Other differences include a solid crown vs. hollow crown and plain gauge uppers instead of the butted.

Even with all these differences, the weight difference is approximately 200 grams more (than the Auron). The retail price for the Aion will most likely come in under $600 whereas the Auron is sitting at $700. The Aion will be available in 27.5 or 29 and it will be coming out later this summer.
