I would appreciate recommendations for a substantial rear rack. I've looked at a lot online and in person, and they seem to be much of a muchness.
I'm looking for something rock solid, that extends as far back as practical.
As a touring cyclist as well as a commuter I am a big fan of Tubus racks. Light and very strong. On my Surly Long Haul Trucker I have a Tubus Cargo Expedition but there are lighter options. My front rack is a Tubus Tara. Andrew
