The track i run on is a very loamy dirt track. The problem is its next to a river that periodically floods and dumps alot of sand on the track. My stock bearings in my typhon went out really fast so i replaced them with sealed AVID bearings. I hear these were some of the best but after a few runs all my wheel bearings were crunchy and had sand in them. I cleaned them out where i found a little factory grease left. Typically speaking bearings need to be packed with grease but i tried using some drylube instead in hope that it wont attract sand. Curious if anyone else has tried this or can share their bearing maintenance tips or proper care that i should be doing. Thanks guys for your help and info.
