The Shadow Conspiracy Slide Or Die (S.O.D.) hub guard is Scott Ditchburn's signature model made heat-treated 4140 chromoly with a proprietary nylon/fiberglass sleeve to reduce drag when grinding. The S.O.D. guard is designed to slide over the non-drive side hardware of most rear hubs, protecting the spokes and hub flange from grind damage.
Note: Universal type hub guards will not work with most 14mm female axle hubs that use 3/8" axle bolts. However, if the hub uses 14mm female axle bolts, it should work fine.
