I've got a 1981 Apollo IV that I've been using as my daily commuter and in the last couple of days it has developed a knocking noise from the BB. It's not constant and at times it's not there at all but often when it's under load and also after going through a bit of water you can hear it and feel it a bit through the pedals. When I got home today I had a closer look and there is a noticable lateral movement in the cranks - if I grab a pedal and move it away from the frame the whole crankset moves - not by much, maybe a millimetre or two, but definitely an obvious movement.
I don't have the tools to remove the BB so I can't tell if it just needs tightening or whether it is more serious. The question is, is it safe to ride for a few more days or should I get it to the emergency ward asap?
