I bought a paddock bobbin head, a spindle bobbin head, and a fame slider. All were exactly what I wanted and shipped quickly to Seattle, WA. NOTE: These replaced identical items that were victims of a rainy day, track-session low-side at The Ridge Motorsports Park. So this isn't just a review of a nicely built product; these sliders actually work perfectly. The bike -- KTM 790 Duke -- came out of the crash unscathed -- except for the Evotech protection. Thanks, Evotech. You guys should start making condoms. ;)
