2013 Avid Elixir 5

Hi pair of avid brakes taken off demo last year after a few rides and kept for spares or to put on my xc bike!!! Guess what never needed as yet so looking at letting someone get the use out of them rather than gathering dust for another year, the rear was split to get off bike from what I can remember but they wr always kept with good oil in but prob need bleed due to time since used.
One had piggy back clamp on so would need replaced, only a couple of quid. I have some part worn pads if any good and a selection of mounts etc if I have the one you want I will send it. 185 and 160 avid discs if needed also.
Many thanks for looking and any questions please ask. Just looking to sell so thanks but no freddos curly wurlys or Xbox games etc etc!!
