Charlie says... "These are the best EBBs we have ever used. No more slipping and adjusting. They can be used on non-niner frames, just need to get the BB shell faced "
No more creaks, no more rounded EBB shells, no more debate about which system is best. Niner’s new Bio-Centric bottom bracket system eliminates ALL of the issues with any eccentric bottom bracket system in an amazingly simple way.
The Bio-Centric EBB 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 Bio-Centric 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.
