Hi folks, I've been riding my V10F for about 10 months now and I love it. My only complaint was that the trolley handle is way too loose. It kinda ruins the experience of pushing it around or even propping it up against a wall. A couple months ago, I commissioned my good friend to help design a spacer to fix the looseness of the V10F handle. We've gone through several designs and materials before finally settling on a final version. I've been using this version for a couple months now and the handle feel is super tight and perfect! If anyone is interested, we've listed a kit on Amazon at a modest sale price of $15. The kit includes various sized spacers and the tools and instructions needed to install. Let me know if you have any questions!
