There are two seasons in Oregon: "Winter" and "Fire/road construction". I last rode about 5 days ago because we've been having 95° days complete with thunder storms. When I last rode, there was fresh chip seal (Macadam) right at the beginning of the 200+ mile ride. I neglected the bike for a few days after the ride and finally today I looked things over.
The belt had a scraped up appearance with grooves over the entire length, on the toothed side. Upon further inspection there were small stones glued to the rear pulley with tar -- that wonderful chip seal. I spent about an hour with various scraping tools removing the rocks, most of which shattered when scraped. They were in dry, cured tar and were difficult to remove. There was only one stone trapped in the front pulley, thankfully.
The belt is a little frayed looking and the scars are probably 1/32" deep. You can feel them with you fingernail. I'm going to run the belt at least til my next tire change, which will be in about 1500-2000 miles. If it's deteriorating further then, it will be replaced.
The Kuhmo Ecsta PS-31 rear will have about 9000 miles on it when it needs to be replaced. 1.5mm to the wear bars. It's been great for traction, but the life time was a disappointment. I'm not sure what I'll replace it with.
Did I mention that I really like shaft drives?
