| Apr 26, 2020 at 18:35 | comment | added | Swifty | I can see the depression in the rim tape, and also at the edge that it has pulled the tape down from the side, there is a little deviation in the edge of the tape. The one bump certainly lines up with the spoke. I expect the tube was able to push the tape further into the spoke hole when the tyre was on and all inflated up to 100psi, and maybe was chafing. However it isn't anything I've seen before so I'm speculating a little. Hopefully someone can give a solid explanation as an answer | |

Make a couple images larger for easier viewing

| Apr 26, 2020 at 18:28 | comment | added | Will Haley | Done, and thanks! I added a photo showing that the bumps are very close to the spoke hole. It's the third spoke from the valve. I also added a photo of the rim tape. I think it may be difficult to see the depth of the depression, but I feel it. You can only see a slight discoloration of the tape in the photo. The depression is in the center of the red circle. | |

Add some images to better illustrate the issue in relation to the wheel and rim tape
|
| Apr 26, 2020 at 18:07 | comment | added | Swifty | Could you add a photo of the rim tape at the affected area? I suspect the tape is letting the tube push into a spoke hole but may not be the case. Are the bumps directly opposite the valve or some other point on the clock? I'm wondering why there should be two | |
