Which one is the 20mm adaptor?
Found these both, but unsure if they are both needed or if it’s just the one…?

On the left is the 9mm fitting which is a press fit into the bearing due to the o-ring.

On the right is the 20mm fitting which sit loose on the bearing and are held in place with a circlip.

Use one or the other.

So basically, I send both parts just to be on the safe side to the buyer from the classifieds.

Oh and thanks 🙂

No, if he wants 20mm, sent the packet on the right, if he wants 9mm send the packet on the left. If you’ve got no use for the leftovers, might as well send him both. In my experience, not many people need the 9mm qr ends. That’s what most start with and move away from. I don’t see anyone going the other way.

edit – I’m being stupid. I’ll be quiet now

Yeah I did think as much, ok, sorted!
