    Chris King BB now available in BB92

    Might be old news to some, but it looks like the BB92 version of the new Chris King bottom brackets are available.

    I'll be ordering one for the Ripley

    Nice! Thanks for the heads up. I'll definitely be swapping out the Sram BB for the CK. Looks like for those using Sram GXP cranks that you'll need the Conversion Kit #6 in addition to the BB....

    Correct. I already have a conversion kit from my threaded King BB. Same parts in case you already have them.

    since the SRAM is $50 "around", it would be hard to justify the $250 total expense for this plus the GXP adapter. I already have the "injection tool" that helps these last for years, but thats still 5 years of a new SRAM BB every year before one breaks even.

    IME, the Sram one, while it does not last as long, spins way better. The GXP conversion for the CK it's not the best approach. It rarely has a good fit, meaning, you either get a bit of play or drag. Now the CK BB for Shimano/FSA/Race Face applications it's the way to go! Thou the Race Face BB seems solid and it's also serviceable.. and cheaper...

    The ceramic bearing version of the SRAM is around $150.

    I've got a traditional (thread in) chris king ceramic with the gxp conversion on my hd and it works great...not had the above-mentioned issue with getting it set up correctly.

    Sure, but while I can sorta see someone buying a ceramic BB for a road bike that they race, this is for a mountainbike that I don't. I don't even use ceramics for the 'cross bike I race every weekend. Its just too wet and muddy here in the PNW, and you go through BB bearings if you ride a lot year round.

    As a basic assumption, at the (approx) 90 rpm that we turn cranks, what sort of watts does a ceramic BB save us? Could it possibly be worth $100?

    "In the December 4, 2006 issue of Velo-News there is a very nice article on page 40 by their technical editor Lennard Zinn. In the article Zinn compiles a chart of test data that compares the rotational resistance of, among others, an FSA Mega EXO steel ball bearing bottom bracket as compared to the same bottom bracket equipped with ceramic bearings.

    His test results reveal an end result of .09 (nine one-hundredths) of a watt difference in rotational resistance. For the remaining results see the chart and test protocols on pages 41 and 42 of that issue."

    On a related note, King BB92 bottom brackets are available in steel bearings for $145 (conversion kits extra $16-22)

    Given the ability to flush the bearings and choose your lubricant, this could be certainly worth $160-170
