What are the horizontal slots/tabs on the back of some saddles for? Some saddles like Brooks have two tabs sticking down from the back, with a horizontal slot through each. What are these for? My guess is they are for certain kinds of saddle bags, but I don't really know. Is there a name for the slots (e.g. if I'm looking specifically for saddles that have that feature, what do I search for)?
You're totally right - they're for saddle bag straps.



I don't have a search term, but the word "roll" might get you further.
