I'm trying to figure out why my spokes would have broken during the same exact climb twice. I am using 11/12 gauge spokes on a dirtbike rim. Tension is checked before each ride. I would say that I tension very tight.
I've beat this rim to death, over 20 rides before I broke 6 spokes yesterday. Everything from, jumps, climbing lots of stairs, running over curbs at high speeds, nothing seemed to break the spokes. Spokes were all broken at the elbows all in the same location.
I replaced the 6 spokes yesterday and today checked tension a few times during the ride and everything was tight. I even beat the bike hard to test my shock today. Then I decided to do the same exact climb that broke my spokes the previous day. I could not believe I heard the same loud BANG as yesterday, and noticed 5 spokes (maybe 6 as one spoke looked to have pulled out of the nipple) were broken at the elbows all right next to each other.
I'm just confused and was looking for any insight into why they would break at this same hill when I never had any problems anywhere else. I wasn't even going very fast as you can see in the videos. The only thing special about this climb is that it is a steep little hill with maybe a 6 inch curb at the bottom and when the tire hits that 6" curb the spokes pop.
What is also interesting is that I broke 6 yesterday and heard the pop I didn't realize I broke the spokes, then I actually climbed it again maybe twice more with probably all 6 spokes broke and the wheel didn't fall apart.
The first time I climbed the hill today I heard the POP and noticed 5 spokes broken.
What confuses me is why is it breaking only at this exact climb, and why after breaking 6 spokes am I able to do the same climb without the wheel completely falling apart? I would think if it was able to break the first time when the wheel was fully built, after losing 6 spokes that it would surely break completely.
Could I possibly have my spokes tensioned too tight?
Bike is a torque raptor bike, with a Downhill rear bike shock that has 10" of rear travel.
First video when I broke 6 spokes, you can hear the POP.

Another angle of the climb, this was right after I actually broke the 6 spokes and am driving with 6 broken spokes without knowing they are broken.
