Raleigh - and others - MADE everything.
Tyres, ball bearings, ratchets, chains, handle grips, frames, saddles the lot!
My point above is that a daft business model like that led directly to Raleigh making an awful lot of duff bikes and ultimately to their demise. What exactly is the point of making bearings and other small parts yourself which are expensive and poor quality when you can buy good quality bearings or whatever in for a fraction of the price made efficiently by a specialist? If Raleigh hadn't been so pig headed maybe they'd still be in business.
There was very little that Raleigh did well. I'd have thought trying to restore a Chopper would have made that much painfully obvious. I remember as a youth working in a bike shop. I dreaded having to put new Raleighs together - they were awful, although some of their top end stuff from the special products division was good.
