Moog K6187T Caster As one reviewer said, no used materials here? great stuff here. Installed in no time (if you know what you're doing) and tightened the handlebars hands down. Now my handlebars are tighter than a frog butt LOL and it's tight: I removed parts from another brand that only lasted 6 months, if that's the case don't make that mistake! Buy the best of MOOG first (DO NOT BUY TWO PIECES) but with RagenRat's confidence
