handling restored after original bearing cage got crushed!

So far, this headset is super smooth and nice for the price, a solid upgrade from my loose ball bearing cage that came with the bike. The sealed cartridge bearings are doing a great job thus far.

Perfect upgrade for a northrock XC00

I returned 2 sets of the 44/56 because I ordered the 44/50.6 and they kept sending the wrong one. I received the 44/50.6 and installed them today with no problems. Perfect upgrade for a northrock XC00. Remove the old cups and bottom race and it slide right on. The steering is amazingly smooth now. I should have ordered new spacers because the new bearings have a short dust cap, so I have the old dust cap stacked on top to make it work. It's not a problem, just not as clean and hides the upgrade under the stock cover.
