Profile mini front hub guard. Made specifically to fit the Profile mini front hub (or Madera Pilot V2) with 3/8" bolts.  Will work with the Profile Totem front hub as well.  Press fit onto hub center axle, replaces grind side bearing cone, installed but never bashed, still goes on and off with ease. 7075 Aluminum, made in USA.  The new Aegis front guard sells for $35, I think these were $25 or $30 new.
