If it extended the time between tune ups.....

Would you install ceramic loose ball bearings in your commuter hubs?

Understanding that there are no real performance gains in the commuter range unless you commute 100 miles or more.

I spoke to Boca Bearings and asked them about water, maintenance, grease, and life span in steel or alu races.

Basically they wont rust, grease is optional and it can be any bearing grease, and the bearings will actually outlive the races. Some papers even suggest that the races will wear better with ceramic. I assume this is because the #5 ceramic bearings are smoother, aka rounder, than #25 steel bearings.

My bike is like my car. I put in quality parts so that I don't have to screw around with it and things tend to go sideways less often.

Yes I understand that #25 steel would be just fine and has been for years. However, you still have to grease them and if the are soaked in water as happens here in the PacNW you can develop all kinds of issues later.

Just a thought.

Time for a cost/benefit analysis. Me? No, I only repack once a year or so. If I could get a complete set of bearings for the bike for $10-20, I might think about it. IIRC, the ceramic bearings are about $10 a pop; $400 for a bike? That's what cold, wet Saturdays in winter are made for, repack the bike's bearings so you can't go for a ride.

Not worth the money. Nice, but not worth it.

Bearings for 20 3/16" loose balls $32

Bearings for 18 1/4" loose balls $40

All bearings are grade 5 Silicon Nitide?? Si3N4 for you chemistry people.

I am sure if you asked you could get grade 3, but that would be silly.

$72 for peace of mind re your bearings, races, and rollability.

No, the sealed bearings used in mine are good enough.. Schmidt, Rohloff.

the races will still pit, with contamination from grit..

I actually read somewhere that due to the hardness of the balls that they will grind the dirt finer and reduce the wear on the races and balls.

Not real sure I buy that.

I can get a whole wheelset with Mavic A319 rims and XT hubs with 36 spokes for $200. I can go 5 years on them without any maintenance. To me, the ROI of ceramic bearings is way too low for commuting. On a racing bike, maybe, but not for a commuter.

Well, I have 24,000 miles on my bike, about 10,000 on the current set of $100 each wheels, and the extent of maintenance so far has been to power wash the bike a dozen times a year or so. I've never even repacked. And as far as I can tell, everything's still running fine.

I have not had a tuneup either. I have replaced the bottom bracket once. I'm on the 2nd front wheel but just because I switched to discs, and the 3rd rear, first rear was factory junk and broke spokes, the 2nd I built but the axle broke after about 13,000 miles. Never had any trouble with wheel bearings.

So I guess no, I wouldn't pay any extra for ceramic bearings.

$25 gets me a full replacement set of cartridge bearings, front and rear. Even if I replace them after every single CX season that's 3 years worth for $75, and no farting around with cleaning and repacking. Slide hammer the old ones out and press the new ones in: 5 minutes, including the time it takes to put my bike on the stand and remove the wheels.
If I was racing Cat1 or Cat2 and really looking for performance advantages, I'd consider it. But for schlumpy here-for-the-beer class racing, nah. Can't justify the cost.
