cartridge hub bearings

I just got a new wheel set and was initialy confused by the catridges in the hubs. I never rode or worked on a bike with these before. At first I was pissed at the bike shop for not putting any play in the hub. But checked around and found out what they were. So im wondering if any on-line tutorials exist for how to work on these. Also, these seem pretty stiff. Are there any good after market bearings in this area?

If they are new, why do you need to work on them?

Are you saying that you want play in the bearings?

Can you post pics of the hubs or give a link to a site about them? Hard to know what to recommend without knowing what hubs they are. I don't deal with many Cannondale hubs but I know of some Coda hubs from Cannondale that used DT Swiss Hugi internals. I might be able to help you if it's similiar to those.

I had a set of Coda cartridge-bearing hubs on a C'dale T2000 a few years back. They used standard-sized bearings (B6000 and B6001) that are available from many sources... I got my replacements from www.biketoolsetc.com (they are a good source for all sorts of other parts as well). I made a tool to press new bearings into the hub body from a large diameter hardwood dowel. Replacing the bearings was very simple: tap the old ones out with a plastic hammer and my homemade tool, then use the same tool to press the new bearings into place. It only took a few minutes.

I sold the C'dale a couple years ago, so the hubs are gone. However, I have a BOB trailer that uses B6001 sealed cartridge bearings in its hub. The bearings press in just like those in the Coda hubs.

Hope this helps. Have fun.

Probably no ones reading this anymore. The hubs are marked as cannondale fire. They use Dt swiss spokes, possibly internals. Basically when i pop the cover off, it looks like a skateboard bearing. I was just kind of confused initially by how tight it was.

new cartridge bearings are tight but smooth, if you are used to good cup and cone bearings. just use them.

They'll wear a bit looser with riding time. I'd leave them.

Depending upon the design, some cartridge-bearing hubs squeeze the axle when the QR is tightened, needing some play. Other do not and should be adjusted with no play. I'm not sure what kind you have, but a simple way to check is to count the number of back & forth sweeps the wheels make with and without the QR tightened.
