Omas "Big Sliding" bb for sale.
English thread, 109mm axle length.
Threads on shells and lock rings are perfect.
I'm presuming this is the titanium version as nothing other than the bearings are magnetic.
Bearings are very smooth. I think this is the first time it's seen daylight since it was fitted to my lopro when new in '94, a bike that's seen little use anyway and only in TT's.
You can dial in your chainline better with this BB as both shells have lockrings.
£75 posted uk mainland only.
