Ridden by 90+ kgf rider 10-15,000 km/yr for about 7 years in hilly terrain.
The root cause fo the failure is unclear. Some similar failures have been attributed to tubes not welded inside the junction, 'fixed' by manufacturing so one tube is welded completely to the bottom bracket shell, then install and weld the other tube.
