I'm actually considering a Tubus Logo Classic Edelstahl (stainless) for my new bike. I live and ride near enough to the sea that I don't want to risk rust, and aluminum/aluminium racks tend to not last more than 5-10 years for me; this makes stainless the "affordable" option.
The "regular" version of the Logo has small "nubs" on the rails (red circle, pictured below), apparently to keep the pannier hooks from sliding backwards. Those nubs seem like a good idea…
But the stainless version of that rack does not have those nubs.
Aside from wondering why the nubs are missing from the stainless version (my first guess is that it has to do with nuances of welding stainless steel) I'm wondering how the lack of nubs affects the functionality/usefulness of this rack.
Anyone have experience with one or both versions of this rack?
I'll most certainly be using Ortlieb QL2.1 back-rollers with it.
