I've 3 bikes with Shimano bmx-style freewheels and never seem to get very long out of them. I admit to riding them through crap and seldom cleaning them (thought that was the point??) but even so I think they should last longer than they do. This morning's commute involved a walk home after one that hasn't seen much use packed in without warning. It had got covered in crud which I hadn't washed off, but its pretty new so I'm a bit miffed.
Is this just the way it is with these, or is there something I can be doing like cleaning them and smothering in grease? Or am I better to bite the bullet and splash out on WI ones?
