Dude, I've set up 2 Blunt compression sets before, and let me tell you, it is the shittiest compression there is. It took me a while to get it figured out the first time, but then I got it. Came loose after like 10 minutes.
Then on another scooter, I already had it all figured out, and then I set it up perfectly in like 5 minutes. Still came loose after 10 minutes.
It's just a fail at trying to make starnuts reusable. I would rather just buy a new one for 2 bucks for each bar I have.
