+1 on not using ceramics all around. Save yourself some money and use the standard metal shielded bearing inthe hubs and you will be fine!!! I use Avid bearing in all my cars and trucks. The price for a ceramic set at Boca is like $95.00 I think for the TC5, it is not wrth that kind of money, one good hit and the bearing is toast anyway!
I usually buy like two dozen bearings for 24 boucka nd that will last two seasons, unless you replace them all the time.
