I’ve had OG fox 36s, lyriks, and Pikes that have creaked in the past so definitely not foreign territory:).
Head angle, our terrain, the way we ride, as Andrew stated earlier, has to be the main factor. I work in aerospace and see a variety of metal press fits day in and day out. Corrosion, even on surface finishes we may consider almost perfect, is expected. Sooo, I vote for 1 piece CSU’s please.
On my 36 CSU #3 I’m still troubleshooting the usual, dirt, headset cups, etc....but it’s the usual sound we all know when the cracking starts. My CSU #1 was warranted under the 1 year time frame. I think #2 was out of the 6month window warranty for the replacement, he see the $fee. #3 I’ve been told when I got the fork serviced with the new crown, that Fox will charge a replacement fee on that if it needs changing. I will say, Andrew and Natalie at SW have been amazing as usual. I remember Natalie equally expressing frustration over this at the time. It is what it is. Perhaps I’ll look to Ohlins or another variety when the time comes.
