Rated 3 out of 5 by 1 reviewer.
Rated 3 out of 5 by Will not fit a standard PF30 or BB30 bottom bracket The product rating I have given is irrelevant. I bought it to do something it was not designed to do, the descriptions are incomplete/misleading. The descriptions should be changed from "Press Fit 30 BB Shells" to "Chris King PF30 Bottom Brackets. The Chris King Press Fit Conversion Kit #2 will not fit a standard PF30 (or BB30) bearing. It will only fit a Chris King PF30 Bottom Bracket after the removal of the plastic spindle sleeves. http://chrisking.com/files/upload/instructions/Conversion_Kit_2.pdf Most PF30 & BB30 bearings are 6806 (OD 42mm, ID 30m, Width 7mm). The bearings in the Chris King PF30 Bottom Bracket are not, the ID of the bearing is greater than 30mm and the plastic sleeve reduces the ID down to 30mm. 12 August 2014

How to install?

Hi,

I have purchased a Chris King adaptor kit no. 1 to convert a PF 30 bottom bracket to enable the use of my Rotor cranks with it. The part of the adaptor to go into the bearing is larger than 30mm and so will not go straight in.

The installation instructions say: "Be sure to remove both spindle sleeves (black plastic pieces) from the inner diameter of both bottom bracket bearings by hand before installing the reducers"

The only black plastic pieces were on the outer face of the bearings. With these removed the bearing is exposed with its silver metal casing inner and outer holding the bearings together.

If the inner metal ring is removed the remaining aperture would appear to be the same size as the adapter. If I remove this ring though surely the bearing is destroyed or it all comes out?

Please help.

Thanks,

Steve

I am purschasing a Specialized Venge that has a OSBB ( which I understand is 0.5mm bigger that BB30 )

What I need to know is there a BB adaptor that will go from the Specialized OSBB to fit my BB68 Shimano running gear.

Please note that OSBB and BB30 are not the same size, OSBB is 0.5mm bigger and this will have small amount of play and movement. Also make creeking noises under load.

Please help?
