I hope I am not doing anything against the rules if I let people know that I put this handle set up for sale on Ebay. It is listed there as “Nimbus Shadow Handle Set for unicycle - Matte black handlebar, complete, unused”. Here: https://www.ebay.com/itm/224235694380?_trksid=p2471758.m4704
I bought it as a replacement for one that broke from too many spills (a Qu-Ax) but then I fixed that one and no longer need this one. So it is all new, just not in the original box.
[Thanks to all for the posting advice, sorry for being a cyber-idiot.]
