Couldn't work out why. The LBS (a decent one) eventually found the problem: water thrown up by the rear wheel, hitting the underside of the seat and going down the open end of the seat-post (must have been pretty wet that year!). As we all know, the seat tube and main tube ends protrude into the BB shell, so water gathered inside the BB shell over time and naturally seized the bearings. They were able to thread the BB shell and replace with standard removable BB lock-ring. Then last year I had the BB shell properly overhauled: the tube ends reamed out of the BB shell so that it can take standard BB set. But apart from the top of the seat tube fatiguing and developing a crack, I've had no other structural problems from the bike (and that's included transporting two children on the back!)<br /><br />My other Viscount, an Aerospace Victor, has been ridden little in its life and still has the original BBs and spindle intact and working well.<br /><br />Great blog!
