Ello, 
 
 Picked up my first trials bike in 12 years today, good price but its in need of a few jobs doing. There was a little bit of play in the bottom bracket so I got the cranks off and went to tighten it up, one end was accessible as normal with the BB tool, other end I was greeted with this.... 
 
 
 
 
  So, in short, Do I need a new BB??   Thanks
