BIOCENTRIC COMPATIBILITY
The BioCentric is only designed to fit in Niner frames. It can sometimes be
made to fit into other manufacturer’s frames but it will not work properly.
The BioCentric clamps to the outside face of the EBB shell and because
of that it requires that the EBB shell be precisely faced. This facing is
something that can only be done at a machine shop, or in the case of
Niner frames, at the time of manufacture.
Some older Niner frames may require extra steps for installation.
If you have a used/older frame or if your BioCentric has 130 in/lbs laser
etched on the non-drive side shell, contact [email protected] for
instructions.
ABOUT AFTERMARKET PF30 EBB UNITS
There are currently eccentric bottom bracket (EBB) units available from
several sources that are compatible with PF30 bottom bracket shells.
While these are approved for use with our alumnium frames, the clamping
force could damage or destroy the bottom bracket shells of our carbon
frames.
DO NOT USE AFTERMARKET PF30 EBB UNITS WITH
CARBON NINER FRAMES!
