    Has anyone installed a King PF BB on a Mach429c?

    I just picked up a set of Race Face Next SL cranks for my wife's Mach 429c. They have a 30mm spindle so I need to swap out the BB. I have been searching all over, but have not found any references to using a Chris King pressfit BB on a Pivot with PF92 frame.

    Anyone tried this?

    There is no King bb that will do a 30mm spindle in a PF92 shell.

    I have one installed on my Pivot Les but I'm not sure if it's the same size as a 429

    I have a 24 (cited in OP link), going on 2 years. Seems great even tho folks say it should be barking by now. Have babied it tho, no rain or mud and live in drought-ridden area.

    Chris King does not have a PF92 BB for 30mm Spindle that I know of, I looked a few months back. That BB shell is only a 41mm diameter. However there are manufacturers that do make them. I used the Enduro version at enduroforkseals.com on my Pivot Les Fat. I actually use the RF Next SL crank on that bike. I think that RF is coming out with one, but I do not know if it is available yet. I'm sure there are or will be others too.
