Metric sizing allows both suspension and frame manufacturers to significantly simplify rear shock sizing and fitment, while also providing performance benefits to both suspension and frame designs. A significant number of major bicycle manufactuers are now spec'ing metric Deluxe, Super Deluxe and Super Deluxe coil rear shocks.
Metric shocks still require 3-piece design hardware for mounting. Check with your frame manufacturer to verify the hardware size needed.
Sized by bolt diameter (M6, M8, M10) and frame mount-ID width (in mm).
Two hardware kits required per shock: 1 for each eyelet, or one hardware kit required for Trunnion mount rear shocks.
