EB18: New & prototype SR Suntour rear shocks, New Durolux 27.5 Boost & coil forks

The new SR Suntour Edge rear shock replaces their UnAir and DuAir models, combining them into a general purpose air shock with external rebound control and your choice of a remote or switched compression lockout. But that’s not what you’re seeing above. That unmarked rear shock is the upcoming Edge TT, for Twin Tube, and adds more features and bigger volume. To see how it’s different, let’s look at the new Edge first…

Available in standard, metric and Trunnion mounts, the Edge is a basic air shock that can be ordered with a full lockout (LO-R) or their 80% lockout (called LO-R8) for riders that just want to firm things up without a complete lockout.

Internal spacers let you adjust the air volume, and it can work with a single or dual remote lever (the dual works the fork simultaneously). They’ve also updated their remote:

Ever launched into a downhill section and forgotten to unlock your suspension but couldn’t relax your grip enough to do it? SR Suntour’s brilliant release mechanism puts a flat paddle perpendicular to the grip. All you need to do to open the suspension is nudge your hand in its direction and you’re ready to rip.

That remote will also work with the new Edge TT when it comes out. No official details on this shock were available, but we can tell a few things from appearances. The “TT” moniker means Twin Tube, which refers to an additional air chamber surrounding the main air chamber, so there’s more air volume.

There’s also a dedicated low-speed compression adjustment knob separate from the lockout. No word on when it’ll come out or price.

When the modern incarnation of the Durolux debuted, it was a 27.5 fork with a 20mm thru axle. Then the 29er came out and used a standard 110×15 Boost axle. Now, the 27.5 model will get that axle, too, making it a little easier to fit more wheels.

The Durolux received a damper update recently, too, switching to a simpler system that lost the external high-speed rebound adjustment. Internally, it became a bit more robust, though, and, honestly, most people won’t miss that particular knob. Travel options are 160/170/180mm, claimed weight is around 2,155g.

For more budget minded riders, the new Zeron borrows the same 35mm stanchion chassis as the Axon forks, but goes with a coil spring and basic preload adjustment knob on the left. Damping has a simple low-speed rebound knob, but word is you might be able to fit their higher end RC2 cartridge in there if you wanted more control as your budget and skills improve. It comes only in Boost configuration, for 27.5 and 29er, with 130/140/150mm travel options. Claimed weight is 2,480g, and it’s e-Bike certified, too.
