It’s definitely a bearing. Size 6900-2RS with a hollow metal pin/rod that goes through the middle. I’m about to do a full bearing swap on my frame, except those two bearings in the shock shuttle as they seem fine for now.
I bought a full set of 2012 Spicy bearings from Kaetec on ebay – he does single bearings too, as do a lot of others on ebay/internet. Just make sure it’s decent quality.
The bearings are pressed in from each end of the shuttle so i reckon a punch through from the hole in the middle of the opposite bearing to get them out. And then a 6900 open-bore drift (just found that wheels manufacturing do these in loads of sizes for £5.50ish each – so i’ve got all 3 sizes for the different bearings in the spicy and a threaded rod to use them with for under £20 – Much cheaper than getting someone else to do it)
