Today, when I went to the basement to do a workout on my trainer, I noticed I had a flat (rear wheel). After my initial frustration, I decided to fix it instead of procrastinate. I remove the old tub, installed the new one… then I noticed a bump in the tire around the tube valve.
I’m not gonna lie, I’ve seen it before but I shrugged it off in the past. This time, when I spun the wheel (already back on the bike) I could tell there was a lot of vibration around that area and once I gently put my hand on the tire, I could easily feel the bump. Alright, there’s something wrong here, let me try to fix it.
If you look at the photos above (especially the first one), you can see that the tire is not back inside the bike wheel rim. I tried everything, but I couldn’t fix it. It seems like the tube (and the valve) is taking a lot of space and it blocks the tire to get inside. Look at the next photo to understand what I’m talking about.
I don’t know what to do. I thought I might be using the wrong tube/tire sizes, but I don’t think that’s the case. These are the specs for everything:
What I am doing wrong?? I feel so useless. Any help is appreciated.
