    BB30 ceramic bearings

    I have had my new Scalpel for 2 months now and I started to hear severe creaks coming up from the BB area. I thought I might have to put some additional grease on the different contact areas, but when I took the crankset apart, I noticed both of the bearings are already worn How is this possible?? I wash my bike every week (no high pressure water of course) and I am always careful not to put any water on the BB-area. I am sorry to say, but these bearings are rubbish!

    Are Enduro bearings any better than the C-Dales? Are there better alternatives?

    When you spin them with your hands, you feel they don't run smoothly any more. When I took off the seals, I noticed the grease between the balls was gone and the race was completely dry. When I stood on the pedals, there was this constant creak. In the meantime I did some searches on various internet forums und it appears it is a common problem with the C'Dale ceramic bearings. I ordered som Enduros now. I hope they will last a little longer

    ok here is the big question how do you remove the bearings?

    i guess since it's BB30 i don't have the tools at home to do this eh?

    protection from dust in both sides

    cheaper than stock ceramic bearings ... here in italy a pair is starting at best price at 80 euro to grow up

    If you are sure you don't need the bearings any more, you can simply knock them out using a screw driver and a mallet. If you plan to re-use them, you need a BB30 bearing removal tool (available from Cannondale or Enduro).

    hi guys, kicking this thread back up as i'm having similar issues with my bb bearings. i was looking at either:

    1. http://www.universalcycles.com/shopp...s.php?id=21944 (SI BB bearings (6806) - pair). they look like they are just standard bearings. US32 for a pair.

    OR

    2. http://www.superflycycles.com/servle...ro-Zero/Detail US52 for the pair.

    is the one from universal cycles sufficient or should i look to get the enduro? i dont mind spending the extra money if they are going to last a while.

    It could be that. because those rubber seal are to protect the bearing..... It happens to my first scalpel, the ceramic bearing were completely shot... I was able to clean them and re-grease and they work fine, on the other bike, as soon as I got the bike, I took it apart and did not came with it, I installed and havent had a single issue from the bearing..

    Also check that the wave washer isn't completely flat when the crankarms are installed, if it is, it might put too much side pressure on the bearings and make them die faster than they should.
