I have a Trek Allant 7.4, I ride it on the paved trails. I’ve had it for about 3 years. It’s in good shape. Suddenly within the last 3 months I’ve broken 4 spokes on my back wheel. The back wheel is fine. I’ve had the bike shop check it over and over again. The other spokes are fine. I’m just riding when I hear a metallic pop, and the spoke is gone.
Any idea why?
I’ve actually lost weight recently, so I’m not riding at my heaviest weight. If it was weight related I would have broken spokes over the past few years.
Can you put more stress on a spoke if you’re riding slightly underinflated tires? I’ve ridden 3x this weekend and I didn’t check my tire pressure this morning. Worst case scenario they’re running at 60-70 instead of the suggested 80-100…
I read that if you break one spoke it can put stress on the other spokes and weaken them causing this to happen. Suggested getting a new wheel or rebuilding it. Mine are not super expensive so I guess I’m going the new wheel route.
Tire pressure has nothing to do with it. If anything the softer tires should transmit less force to the wheel and spokes. As for riding with broken spokes, you’d need a bunch of broken spokes to create a domino effect – I’m pretty sure the wheel would be wildly out of true before you got to that point. I’d have a bike shop re-lace the wheel with quality, heavy-duty spokes. It sounds like the existing ones are cheap and, like so many other metal objects subjected to stress, have fatigued.
