I have read the other thread about rear wheel bearings.
I am taking my rear wheel off in the near future and trying out a new mechanic whose tire change and balance rate is very attractive. I have 18K miles on the CR and am wondering a few things;
Is there a good simple bearing test I can do before I bring the wheel in?
Should sealed bearings be serviced or replaced?
Is there a generic part number for the 2 bearings?
Is there an easy idler pulley bearing test?

Yep, just stick your finger into the bearing and rotate it. They don't really 'spin' when you do this as they are relatively stiff, but if you can't turn it fairly easily, it's time to replace. At 18,000, it may be a good time to go ahead and swap them out as PM. Non serviceable part. Al has them generally in stock:
Rears wear faster, so generally need to be replaced more often (especially if you have two bearing rear).

is there any aftermarket equivalent that is cheaper and/or superior? ceramic or ... ?
probably beating a dead horse, but while in there... might as well get better bearings if available. Less $ would be a bonus, but not necessarily the only goal.
Buell Race guy (Huff - salt flats speed record racer) recommended an upgraded bearing, but didn't give specifics. But got me thinking!

I test mine by putting as much finger pressure on the inner race of the bearing as possible while I spin it while checking for smoothness and some smooth resistance to indicate there is still some grease in there. I also touch the bearing immediately after a hard ride to see if it is more that just warm to the touch. Mort
