Hi, like flapper35 some months ago, I have just purchased a second hand 2015 crossrunner (RC80) which seems to have a seat that has had work done on it to make it lower (I think some foam removed from the middle and some rubber supplements disassembled). Its too low for me even on the higher setting so I'm looking for a standard 2015 onwards seat either to purchase or swap out mine if someone is struggling to get their feet down enough. Pm me please if interested, thanks.
