Not getting any rattling on mine, and i assembled it myself.
Mine went into a new Yari chassis, with the upgraded ‘YariUp’ damper and smashpot fitted.
I had to return the spring and go for a lower LBS rate as it was way too stiff. Even the one which is 5lbs lower than the chart recommends is pretty stiff. I may even get another one to test which would be 10lbs lower than suggested.
So far it feels great, but hot hugely different to my other coil forks (Ohlins coil in the trail bike, and previous marzocchi 55RC3 ti on the enduro bike)
I reckon, with a lower spring rate, dialling in more bottom out resistance and with a reasonable level of mid speed compression (available on the YariUp) using very little slow-speed compression, it’ll sit very nicely into the mid travel without blowing through too quickly, whilst being very compliant over the small to mid sized chattery stuff.
Great upgrade for an air fork, to bring it inline with coil plushness, but not a miracle-in-a-box.
