Hey guys, I'm new to the DH world and picked up a Karpiel Disco Volante (old school) with a blown rear shock. I'm thinking of putting in a RockShox Vivid R2C in it's place to match up with my Domain Dual Crown. I know it's a rookie question, but I can't find anything on the Googles... is there an industry standard for the outer diameter of the coil? My coil is about 2.0" across, but I'm not sure about newer ones. Don't want to purchase a new shock only to find out that it won't fit my frame. Please help!
