Hi everybody,
I own a Dynabar but I also have manufatured my slider bar. See pics.
Mine is similar to the Ian Alldredge setup using 6mm vectran rope (better than dyneema), a sailing pulley and shackle. I have removed the old hook since I rarely ride unhooked and if needed I use another bar.
https://shop.ride-engine.com/how-to-setup-a-slider-bar/For me this setup is cleaner and safer than dynabar, I use Swivel Snap Shackle instead of chicken loop. Be careful with this and ropes, it may get trapped when you release that is why I use a shackle instead. I love this setup for riding waves
All components are rated above 1000lb, I bought everything in local shop for about 50?.
