C-40 said:I have never done this myself, just read a posting from someone who has. As long as you can get the old bearings out, it's simple to measure them and figure out the standard replacement size, but if they are pressed in with too much interference, you could scrap the cassette body. You generally have to press on the inner bore to remove and if the inner parts comes out, leaving the outer race, the body is probably scrap.
I'd try this shop for better pricing.
Not to be too sarcastic, but wouldn't that depend on the design and quality of the bearings, the quality and frequency of maintenance, and your local weather/dust conditions? The range is huge. The longest I've had a set "last" was 65K miles. Of course they were still working fine and I just replaced the wheel (Campy). I'm now on my second Campy freehub, which has about 45K miles on it.steel515 said:what is lifetime of freehub bearings?
If there's a retainer clip holding the bearings in place, that usually means that the bearings are either a very light press fit or a slip fit. Take the clip out (apparently not easy) and the bearings should come out with little force. When I replace Mavic hub bearings, I use a large screwdriver and a hammer, taping gently around them. A wood dowel rod would also work fine.dead flag blues said:Thanks, curlybike, for the good link. I've got to order some UT BB bearings from enduro..
Not sure where to go to get the bearings pressed out, would a Campy-approved bike shop want to take a stab at this? I'll ask at River City and see if they''d be up for it.
Mr. Versatile said:Depends on a lot of things e.g. how many miles, what kind of weather or road conditions, your weight, how frequently you perform cleaning/maint. of the hub, etc.
I just replaced the bearings in my Record rear hub last week. My best guess at accumulated mileage is 50-70,000 miles.
