Finally got the Fly Proton delivered last week, took it out over the weekend, only to eat shit after doing a bunny hop because the handlebar slipped forward and I went over the bars. Currently have a huge road rash on my right arm. Can anybody see what the issue could be? Fly customer service hasn’t responded yet for a few days.

Not tight enough. Tighten in cross pattern

did you tighten the bars yourself? I usually tighten the crap out of my bars (untill I feel like it’s too much) because I can’t think of another logical reason and you don’t seem to run your bars way chicago or back

To me it seems more space in front (pic3) then the rear (pic4)

If you are desperate, you can use a rotary tool and cut some shallow grooves(left to right) in your stem to give the knurling on your bars something to grab onto. I’ve done it before and it worked 🤷🏽‍♂️. Ultimately, I ended up upgrading my stem and fixed the issue altogether.

The photos aren’t clear but is the clamp area of the stem painted?

I bought a used proton last year and had the same problem. In the end I figured out that the handlebar knurling of the factory bars is flat and didn’t bite in the aluminum of the stem. Bought new quality bars (in my case WTP) and they haven’t moved since. It’s the same issue for you. If you look at the contact area on your stem there are no deep marks of the bar knurling. My trebol stem looked 100% the same. New bars had pointy diamond shaped knurling in contact area that left visible imprints in the aluminum stem. Super solid now.

Fly as in fly racing?

When I was younger I used to put sandpaper to keep my bars from moving.

Looks like you can tighten them down slightly more, but if not try some “carbon grip paste” used for carbon fibre parts to grip eachother but i have found works great for BMX bars

You can tighten bars so much that you deform the bar tubing at the clamp area and that can cause issues…
