    any problems with BB30/pressfit?

    Looking at a Specialized cx bike with a BB30 system. Wondering if any big boys have dealt with these and if they have had problems? I am about 200lbs and regularly toast sq. taper or external types of bottom brackets a few times a season. Specifically wondering about creaking or play that develops.

    Just went bb30 after researching it.

    The install is key.

    Most oe bb30 set-ups are installed dry or with grease. Some creak, some don't. Seems they tend to be a bit more prone to creak than other bb set-ups.

    Anti-sieze seems to work well for keeping things quiet.

    Loctite seems to work best, but obviously makes future bearing swaps more difficult.

    The latest thing is to use rtv sealant.
