Campy copy

I like the style of Campagnolo barrel adjuster with the o-ring but I only found them in M6. The bracket on my head tube is M7 thread. I copied the design and used an o-ring from a broken Gardena hose fitting. 1.13$ worth of stainless steel and a trip to my dad's shop to machine the pieces for my build. Not bad of a deal in my book!!
