Hey everyone, just thought I’d quickly post what I came up with to address the rear rack issue. I don’t think it’s as nice looking as some of the ideas posted above, but it is quite easy and seems to be quite sturdy. Unfortunately, I haven’t really had a chance to properly test it as I’m on holiday right now and not commuting. But I did put my bags on and ride around the neighbourhood for a little bit and it was great. Even over some rough pavement and potholes that I intentionally went over in a way to try and loosen things up, it was fine - I couldn’t move the rack with my hand and I couldn’t detect any squeaking sounds that were driving me up the wall before. I’ll see how it holds up over time, and if there are problems I’ll post them here. Otherwise you can assume that it’s working fine. I ordered an “Orlieb rack three mounting struts” for $20 off their website. I attached these to the seat post (had to replace the quick release handle with a regular bolt and nut) and then had to drill two holes into the rear rack to attach the other ends. This is really no big deal. The rack is just aluminum and any hand drill will work fine. I’ve attached some pictures so you can get a sense of it, but I would say anybody would be able to use the same system and not have to worry about the difficulty of installation.
