My partner has been outside working on the bike, showing me what his new part that he has received from eBay will look like. To me it looks like a long metal tube with a curve through the centre and that's exactly what it is but apparently the technical name is a rear frame loop.
"Wow" the rear frame loop really does make the rest of the bike look rusty and old.... There's going to be a few more quid needed to be spent on this bike..
I have put 2 photos up... Obviously this has not been welded on yet... He was just showing me how it will look!!!
