I have a Prestine Threadless 70mm bottom bracket sealed bearing available if it is of use to anyone. Spindle length is 129.5mm suitable for a triple chainring.
It is unused and in perfect condition. It's complete with crank bolts and 2no. 1.6mm spacing washers.
I bought it a few years ago from SJS to restore a 1982 Saracen mountain bike - one of the first in the UK - but decided not to go ahead and bought a new Raven Tour instead.
