Hey there,
i had extreme knocking/ rattling sounds, always on shaking root lines. sounded like a loose part knocking from inside the frame.
But Nothing to hear when shaking the bike in the stand.
I now searched all the frame internals several times and found that Specialized imtegrated me some secret Swat spare part:
That carbon spacer was in the top tube end near the seattube and rattled as hell !

Perhaps other rattling levos also have integrated secret spare parts by speci assembly line ?
Best regards,
Chris
