My 210 started rattling after some time in the bikepark. The reason was, when I attached the shock pump to check the pressure, the schrader valve came loose and after a while it started rattling. Would be great if the schrader valve had a nut to secure it.
No other issues so far, but I dont ride in the mud if possible. Have it for 6 months now, V2 actuator (when I unpacked it the post slipped out of the box and landed on that flimsy V2 actuator...eeek...it did not break but bent, but it works anyway).
