I can certainly attest to the sheer difficulty of fitting the rubber strap, here's what I've just done to mine (below). Anybody know what size the spring bars need to be to fit a 20mm rubber strap :facepalm:
I've been scouring eBay but I'm not really sure what I'm looking for. I assume I need a 22mm spring bar to allow them to stick out both ends of the strap?

If you have a 42mm PO... then you have 20mm lugs..= 20mm spring bars
