|Who knows about cartridge bearings?||Spoke Wrench|

|I have a 105 headset that has a cartridge bearing that is completely frozen. I've heard guys talk about just buying an industrial bearing as a replacement. My question has to do with the fact that the two sides of the Shimano bearing aren't parallel. A section view through the bearing would be a trapezoid. Is that a bearing that I'm likely to find a replacement for? I'm not going to spend too much time trying to chase a replacement bearing down because a whole new headset only costs $25.00.|

|Most standard bearings are specified by the O.D., the bore diameter and thickness. Never seen one that was not cylindrical.
Bearings are pretty cheap at www.mcmaster.com. They handle a wide variety. Another source is www.biketoolsetc.com.

|I just tried to look this up on Quality's website. They list the bearings for XT, Dura_Ace, Ultegra and that pair of bearings is $20 wholesale. They also list a set marked LX M563 1" cartridge bearings and they are $5.25 per pair. Those prices are wholesale.. most shops and mail order houses will be anywhere from 80% to 100% markup on them. So it's up to you to either take that bearing to a bearing shop and see if they can replace it cheap, or just replace the headset.

|it's a dealer wholesaler, so unless you have an account, you won't get into the site. It has a password and account number access. But it's www.qbp.com
That's Quality Bike Products. Anyone who's ever worked in a shop knows them.. they are the midwest and east coast's biggest distributor. If you own or work for a shop, you can call them and they can help you out.
