Suntour durolux rc, Currently set at 170mm but they are internally adjustable from 180 to 100 using spacers. Really easy job, I’ve had them on my dirt jumper and enduro bike 110x20 non boost axle, so will not work with boost hubs unless you go brakeless A little bit of fading to the stantion coating on the left leg, plenty of scratches and the rebound adjuster has been lost. They work ok, but definitely could do with a service hence listed as spares
