The Avid B74 Shock Standoffs are a direct replacement for the kit standoffs, including (4) 10mm standoffs, and 4 Delrin™ pivot bushings. They are made of black anodized 7075 Aluminum with a 7mm nut as the base to easily install and a long fully threaded stem to help prevent bent shock mount screws while throwing down your Rivkin laps. The Delrin™ pivot bushings are designed to rest against the smooth standoff instead of the screw which extends the life of them however they can be replaced to help maintain a tight fit in your shock cap when needed. And don't forget the added visual appeal of the machined silver rings around the base to blind your competition with.
