1. I'm bothered at the 5000 miles spec. Even in bad conditions, I expect a little more from a rim - unless the OP's brake pads are truly turning into sanding blocks from grit pickup and the like.
2. Open Pro ceramic? That's a lightwieght racing clincher, not an everyday or commuter rim. Think the sidewall problem is solved? Hello eyelet pull through! It's a soft-as-hell rim as well. I've had so many customers go that route and wise up later I've lost count.
Alex Adventurer, Alex G6000, Mavic A719 would be much better choices.
Definitely, disc or drum is something to consider. However, I have noticed from hanging out in shops that disc brake bikes that spend a lot of time in the rain and mud go thru a lot of pad changes in the rear. Same problem with the rear getting grit while the front gets by Scott free?
