The BB (shimano UN300) on my commuter / tourer has worn out after 6 months, is this normal? It gets ridden about 25-40 miles a week, with an occasional longer trip, so not much more than 1000 miles in total. I do have to keep it outside and it's pretty exposed to the elements when locked up at work.
Dunno, rode hard and put up wet from November to April? It's not great, but people have killed entry level BBs quicker. UN300s shall grow not old, as UN55s that are left grow old
