So today I got a flat tire (unrelated, it was a nail, extracted, repaired. All good) and when I pulled over to try to find what caused it, I noticed that my rim was rubbing the brakes the way it does when it's out of true because of a broken spoke.
The spoke is fine. It's the RIM that's been damaged, and that has damaged my calm some. I took it to my usual bike shop, guys are pros, figured they'd have an answer, no such luck. They gave me vague language about how it "looked like it had been hit pretty hard," and that they "see it all the time," but were unable to tell me WHY damage like that could occur, how I could prevent it from happening again, or whether it was something wrong with the rim. They even took pictures of the rim before they handed it back, one was clearly puzzled by it.
Worth noting is that I typically replace my own broken spokes, and true my own wheels; I've been doing it for decades and my proficiency is fair. I don't over-tighten my spokes, if anything my hand is gentle. But the spoke pictured is original to the wheel, so it's not like I over-torqued it with a spoke tool or anything. The spoke on the opposite end, as well as the ones on either side, are also original to the wheel.
Wheel is a Forté Terramax 26", brakes are rim brakes, rim was appx. 2 years old, many miles covered but all on street, all very cautious.
Just looking for answers here, anybody have any idea what could have caused this?
