BB30 life. Lbs spinning a yarn or not?

    I took a relatively new caad 10 back to the shop for it’s free 6/8 week service, mainly due to a creaky bottom bracket that had got worse from basically the first ride.
    After being asked how many miles I’d done ( around 600/700 miles) I was told that this about as much as I should expect from a bb30 before servicing. Needless to say I was pretty incredulous as it doesn’t mention anything on the cannondale brochure about service intervals.
    anyone had similar problems? Am I expecting too much from a modern bb?

    I’ve done nearly 4000 miles
    I’ve done nearly 4000 miles on my supersix and riding it through two winters and haven’t heard a peep out of my bottom bracket. I must be one of the lucky ones.

    But to balance things out, I do get creaking noises out of my head sets on both my bikes, both with integrated/internal headsets. No matter how much grease i chuck in them, or how snugly I tighten the top cap, there’s always a creak when i’m out of the saddle chucking the bike from side to side ~X(

    I’ve got BB30 on my 2011
    I’ve got BB30 on my 2011 Supersix and not had any problems, although having said that I think it may be starting to go as there is a click I can feel rather than hear on the NDS (I haven’t ruled out other causes yet). After three years and probably 10k miles that isn’t unreasonable in my view.

    Like most things it’s the people with problems who shout (not many ‘hey my bottom bracket is working fine’ posts on forums) and while BB30 may have more people shouting than Shimano it’s a long way from that to ‘all BB30 are rubbish – replace after every ride’.

    I’d get the LBS to pop the bearings out, grease or Loctite and reinstall. If the bearings have gone in to the shell dry they will almost certainly make some sort of noise and doing this is quite likely to cure it.

    The bb on my Supersix started making a terrible noise on the non-drive side after about a thousand miles and I thought all the bad things said about bb30 must be true, but I replaced the non-drive side bearing myself, using only grease, and I haven’t had a squeak out of the bb since in almost 3400 miles.

    I was all ready to replace the BB30 on my SuperSix having read about issues with them, but then discovered that my pedals were the source of my clickty clicking.

    No offence taken, I have checked the cleats. They also squeak but a higher pitch. 🙂 The creak happens even using ordinary shoes on the pedals. As it happened from the get go I am not filled with confidence for the future. Thanks for the comments. Also lol at “bb30 sufferers.”

    It’s not unheard of. As hampstead_bandit says, the dreaded BB30 creak is sadly very common. My old CAAD10 needed the BB serviced as your LBS describes roughly every 1000 to 2000 miles or so. I’ve heard the same from other BB30 sufferers in my cycling club too. A heavy dose of loctite left for 24 hours before riding again usually sorted mine out for a good while. If the BB hasn’t been treated with loctite since Cannondale shipped it, I’m not surprised at all it started creaking after 700 miles.

    Make sure your LBS reseat the bearing in loctite for free, and hopefully you should have a longer interval before the next visit…

    BB30 is notorious for ongoing
    BB30 is notorious for ongoing issues with clicking, creaking and short bearing life. Much of this related to bearings fitted dry to BB shell or with loctite, which did not prevent noise as bearings try to move under power.

    PF30 was introduced to alleviate some of these issues, but it had its own problems with tolerance and plastic cups being flogged out by steel bearings.

    I dumped BB30 on my road bike (1week old and already creaking), dumped PF30 on my mountain bike (ongoing creaking, short bearing life) and switched both bikes to Praxis convertor BB’s and Shimano HT2 cranks.

    No problems since, but worth popping the shields on the Enduro bearings in the Praxis BB as they come a little light on grease and benefit from a good smear of waterproof marine grease like PM600 😉

    I had the BB bearings on my Caad8 changed after a year, and 3500 miles (and that includes riding through the winter and a -lot- of rides in the wet). They were not creaking or anything, but not buttery smooth and change was advised.

    (Also, I’m not trying to insult your intelligence… but I thought I had a creaky bottom bracket for a while, but it turned out to be worn out cleets)

    BB30 is a bit naff, but shouldn’t be in need of anything serious at those miles!
