Why the metal seals rather than rubber on clutch in the TQ

The XB8 comes with the blue rubber sealed bearings for the clutch, and the XB8TQ contains bearings with metal seals for this part only.

I plan to install ceramic bearings in my TQ and I wonder why XRAY made the switch for this particulat part. If I do go with the ceramic bearings, should I get metal shielded ones or rubber? (I prefer the rubber seals because they seem to keep dirt out better, though I do realize you lose some performance.) Is the loss that great where I will notice sluggishness if I use rubber sealed bearings? I always fugured you really couldn't tell. Perhaps I should search for ceramic bearings with Teflon or Poly-amide seals?

Thanks for any info on this.

The older Xray blue rubber sealed bearings failed easily. The new metal shield bearings included with the TQ are a MUCH better bearing. I have 3 races on mine so far and they still feel new. Ceramic bearings are incredible and are definitely the way to go. I tear my clutch down often and replace the bearings, so I never saw the need for the ceramics when I could get 2 sets of bearings for the price of one ceramic. Just my 2 cents
