The Shadow Conspiracy Symbol Chromoly Hub Guard Description: The Shadow Conspiracy Symbol Chromoly Hub Guard is designed for riders that don't like having to rotate or replace the plastic guards that come stock on the front Symbol hubs. Plastic guards work well for most riders, but they can't match the strength and durability of heat-treated 4130 chromoly. If you're constantly replacing sleeves or are hard on parts in general, this is the upgrade for you. Just set it and forget it. (2.1 oz) Note: Will only fit Shadow Symbol front hub.
