I will definitely look the spacers over. The biggest problem for a trials bike is that moisture tends to kill wheel bearings and brake shoes. Generally after a trials itís a good idea to disassemble the wheels and clean out the hubs of dirt and moisture but thatís not always possible. Do the ceramic bearings come sealed on both sides?
You can get them sealed or unsealed, or just one side sealed. And the shields/seals are typically rubber, and can be removed or re-fitted at will.Normally the affordable ceramic bearings just have ceramic balls, and the races are still steel, so the races can still rust. But the balls won't. I guess that's half the battle, anyway.
This I do with all sealed bearings. Gently wiggle a tiny flat tool tip in and pop the seals out, flush away the sneeze of shipping grease the factory's are so fond of putting in and re pack the bearing almost completely full with a grease more suited to the environment the bearing will be operating in and then with only thump pressure reinstall the seal.
Hi Ice,Are you sure more grease is better? I would be interested to know from an engineering standpoint.Dave
